ISL60002Precision Low Power FGA Voltage References
DATASHEET
The ISL60002 FGA voltage references are very high precision analog voltage references fabricated using the Renesas proprietary Floating Gate Analog (FGA) technology and feature low supply voltage operation at ultra-low 350nA operating current
Additionally the ISL60002 family features ensured initial accuracy as low as plusmn10mV and 20ppmdegC temperature coefficient The initial accuracy and temperature stability performance of the ISL60002 family plus the low supply voltage and 350nA power consumption eliminates the need to compromise thermal stability for reduced power consumption making it an ideal companion to high resolution low power data conversion systems
Special Note Post-assembly x-ray inspection can lead to permanent changes in device output voltage and should be minimized or avoided For further information please see ldquoApplications Informationrdquo on page 34 and AN1533 ldquoX-Ray Effects on FGA Referencesrdquo

design engineer must take this into account when considering the reference voltage after assembly10 Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided Initial accuracy
can change 10mV or more under extreme radiation Most inspection equipment does not affect the FGA reference voltage but if X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred

NOTES11 Compliance to datasheet limits is assured by one or more methods production test characterization andor design12 Across the specified temperature range Temperature coefficient is measured by the box method where the change in VOUT is divided by the
temperature range (-40degC to +85degC = +125degC or -40degC to +105degC = +145degC for the ISL60002-33)13 Thermal hysteresis is the change in VOUT measured at TA = +25degC after temperature cycling over a specified range ΔTA VOUT is read initially at
TA = +25degC for the device under test The device is temperature cycled and a second VOUT measurement is taken at +25degC The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm For ΔTA = +125degC the device under test is cycled from +25degC to +85degC to -40degC to +25degC and for ΔTA = +145degC the device under test is cycled from +25degC to +105degC to -40degC to +25degC
14 Long term drift is logarithmic in nature and diminishes over time Drift after the first 1000 hours is approximately 10ppm15 Short-circuit current (to VCC) for ISL60002-25 at VIN = 50V and +25degC is typically around 30mA Shorting VOUT to VCC is not recommended due to
risk of resetting the part

Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

NOTES6 Measured with no filtering distance of 10rdquo from source intensity set to 55kV and 70microA current 30s duration Other exposure levels should be
analyzed for Output Voltage drift effects See ldquoApplications Informationrdquo on page 347 θJA is measured with the component mounted on a high-effective thermal conductivity test board in free air See TB379 for details8 For θJC the ldquocase temprdquo location is taken at the package top center9 Post-reflow drift for the ISL60002 devices range from 100microV to 10mV based on experimental results with devices on FR4 double-sided boards The
design engineer must take this into account when considering the reference voltage after assembly10 Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided Initial accuracy
can change 10mV or more under extreme radiation Most inspection equipment does not affect the FGA reference voltage but if X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred

NOTES11 Compliance to datasheet limits is assured by one or more methods production test characterization andor design12 Across the specified temperature range Temperature coefficient is measured by the box method where the change in VOUT is divided by the
temperature range (-40degC to +85degC = +125degC or -40degC to +105degC = +145degC for the ISL60002-33)13 Thermal hysteresis is the change in VOUT measured at TA = +25degC after temperature cycling over a specified range ΔTA VOUT is read initially at
TA = +25degC for the device under test The device is temperature cycled and a second VOUT measurement is taken at +25degC The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm For ΔTA = +125degC the device under test is cycled from +25degC to +85degC to -40degC to +25degC and for ΔTA = +145degC the device under test is cycled from +25degC to +105degC to -40degC to +25degC
14 Long term drift is logarithmic in nature and diminishes over time Drift after the first 1000 hours is approximately 10ppm15 Short-circuit current (to VCC) for ISL60002-25 at VIN = 50V and +25degC is typically around 30mA Shorting VOUT to VCC is not recommended due to
risk of resetting the part

Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

can change 10mV or more under extreme radiation Most inspection equipment does not affect the FGA reference voltage but if X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred

NOTES11 Compliance to datasheet limits is assured by one or more methods production test characterization andor design12 Across the specified temperature range Temperature coefficient is measured by the box method where the change in VOUT is divided by the
temperature range (-40degC to +85degC = +125degC or -40degC to +105degC = +145degC for the ISL60002-33)13 Thermal hysteresis is the change in VOUT measured at TA = +25degC after temperature cycling over a specified range ΔTA VOUT is read initially at
TA = +25degC for the device under test The device is temperature cycled and a second VOUT measurement is taken at +25degC The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm For ΔTA = +125degC the device under test is cycled from +25degC to +85degC to -40degC to +25degC and for ΔTA = +145degC the device under test is cycled from +25degC to +105degC to -40degC to +25degC
14 Long term drift is logarithmic in nature and diminishes over time Drift after the first 1000 hours is approximately 10ppm15 Short-circuit current (to VCC) for ISL60002-25 at VIN = 50V and +25degC is typically around 30mA Shorting VOUT to VCC is not recommended due to
risk of resetting the part

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

NOTES11 Compliance to datasheet limits is assured by one or more methods production test characterization andor design12 Across the specified temperature range Temperature coefficient is measured by the box method where the change in VOUT is divided by the
temperature range (-40degC to +85degC = +125degC or -40degC to +105degC = +145degC for the ISL60002-33)13 Thermal hysteresis is the change in VOUT measured at TA = +25degC after temperature cycling over a specified range ΔTA VOUT is read initially at
TA = +25degC for the device under test The device is temperature cycled and a second VOUT measurement is taken at +25degC The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm For ΔTA = +125degC the device under test is cycled from +25degC to +85degC to -40degC to +25degC and for ΔTA = +145degC the device under test is cycled from +25degC to +105degC to -40degC to +25degC
14 Long term drift is logarithmic in nature and diminishes over time Drift after the first 1000 hours is approximately 10ppm15 Short-circuit current (to VCC) for ISL60002-25 at VIN = 50V and +25degC is typically around 30mA Shorting VOUT to VCC is not recommended due to
risk of resetting the part

Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

NOTES6 Measured with no filtering distance of 10rdquo from source intensity set to 55kV and 70microA current 30s duration Other exposure levels should be
analyzed for Output Voltage drift effects See ldquoApplications Informationrdquo on page 347 θJA is measured with the component mounted on a high-effective thermal conductivity test board in free air See TB379 for details8 For θJC the ldquocase temprdquo location is taken at the package top center9 Post-reflow drift for the ISL60002 devices range from 100microV to 10mV based on experimental results with devices on FR4 double-sided boards The
design engineer must take this into account when considering the reference voltage after assembly10 Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided Initial accuracy
can change 10mV or more under extreme radiation Most inspection equipment does not affect the FGA reference voltage but if X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred

NOTES11 Compliance to datasheet limits is assured by one or more methods production test characterization andor design12 Across the specified temperature range Temperature coefficient is measured by the box method where the change in VOUT is divided by the
temperature range (-40degC to +85degC = +125degC or -40degC to +105degC = +145degC for the ISL60002-33)13 Thermal hysteresis is the change in VOUT measured at TA = +25degC after temperature cycling over a specified range ΔTA VOUT is read initially at
TA = +25degC for the device under test The device is temperature cycled and a second VOUT measurement is taken at +25degC The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm For ΔTA = +125degC the device under test is cycled from +25degC to +85degC to -40degC to +25degC and for ΔTA = +145degC the device under test is cycled from +25degC to +105degC to -40degC to +25degC
14 Long term drift is logarithmic in nature and diminishes over time Drift after the first 1000 hours is approximately 10ppm15 Short-circuit current (to VCC) for ISL60002-25 at VIN = 50V and +25degC is typically around 30mA Shorting VOUT to VCC is not recommended due to
risk of resetting the part

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

NOTES11 Compliance to datasheet limits is assured by one or more methods production test characterization andor design12 Across the specified temperature range Temperature coefficient is measured by the box method where the change in VOUT is divided by the
temperature range (-40degC to +85degC = +125degC or -40degC to +105degC = +145degC for the ISL60002-33)13 Thermal hysteresis is the change in VOUT measured at TA = +25degC after temperature cycling over a specified range ΔTA VOUT is read initially at
TA = +25degC for the device under test The device is temperature cycled and a second VOUT measurement is taken at +25degC The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm For ΔTA = +125degC the device under test is cycled from +25degC to +85degC to -40degC to +25degC and for ΔTA = +145degC the device under test is cycled from +25degC to +105degC to -40degC to +25degC
14 Long term drift is logarithmic in nature and diminishes over time Drift after the first 1000 hours is approximately 10ppm15 Short-circuit current (to VCC) for ISL60002-25 at VIN = 50V and +25degC is typically around 30mA Shorting VOUT to VCC is not recommended due to
risk of resetting the part

Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

NOTES11 Compliance to datasheet limits is assured by one or more methods production test characterization andor design12 Across the specified temperature range Temperature coefficient is measured by the box method where the change in VOUT is divided by the
temperature range (-40degC to +85degC = +125degC or -40degC to +105degC = +145degC for the ISL60002-33)13 Thermal hysteresis is the change in VOUT measured at TA = +25degC after temperature cycling over a specified range ΔTA VOUT is read initially at
TA = +25degC for the device under test The device is temperature cycled and a second VOUT measurement is taken at +25degC The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm For ΔTA = +125degC the device under test is cycled from +25degC to +85degC to -40degC to +25degC and for ΔTA = +145degC the device under test is cycled from +25degC to +105degC to -40degC to +25degC
14 Long term drift is logarithmic in nature and diminishes over time Drift after the first 1000 hours is approximately 10ppm15 Short-circuit current (to VCC) for ISL60002-25 at VIN = 50V and +25degC is typically around 30mA Shorting VOUT to VCC is not recommended due to
risk of resetting the part

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

NOTES11 Compliance to datasheet limits is assured by one or more methods production test characterization andor design12 Across the specified temperature range Temperature coefficient is measured by the box method where the change in VOUT is divided by the
temperature range (-40degC to +85degC = +125degC or -40degC to +105degC = +145degC for the ISL60002-33)13 Thermal hysteresis is the change in VOUT measured at TA = +25degC after temperature cycling over a specified range ΔTA VOUT is read initially at
TA = +25degC for the device under test The device is temperature cycled and a second VOUT measurement is taken at +25degC The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm For ΔTA = +125degC the device under test is cycled from +25degC to +85degC to -40degC to +25degC and for ΔTA = +145degC the device under test is cycled from +25degC to +105degC to -40degC to +25degC
14 Long term drift is logarithmic in nature and diminishes over time Drift after the first 1000 hours is approximately 10ppm15 Short-circuit current (to VCC) for ISL60002-25 at VIN = 50V and +25degC is typically around 30mA Shorting VOUT to VCC is not recommended due to
risk of resetting the part

Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

NOTES11 Compliance to datasheet limits is assured by one or more methods production test characterization andor design12 Across the specified temperature range Temperature coefficient is measured by the box method where the change in VOUT is divided by the
temperature range (-40degC to +85degC = +125degC or -40degC to +105degC = +145degC for the ISL60002-33)13 Thermal hysteresis is the change in VOUT measured at TA = +25degC after temperature cycling over a specified range ΔTA VOUT is read initially at
TA = +25degC for the device under test The device is temperature cycled and a second VOUT measurement is taken at +25degC The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm For ΔTA = +125degC the device under test is cycled from +25degC to +85degC to -40degC to +25degC and for ΔTA = +145degC the device under test is cycled from +25degC to +105degC to -40degC to +25degC
14 Long term drift is logarithmic in nature and diminishes over time Drift after the first 1000 hours is approximately 10ppm15 Short-circuit current (to VCC) for ISL60002-25 at VIN = 50V and +25degC is typically around 30mA Shorting VOUT to VCC is not recommended due to
risk of resetting the part

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

ISL60002
Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient

Applications InformationFGA TechnologyThe ISL60002 series of voltage references use the floating gate technology to create references with very low drift and supply current Essentially the charge stored on a floating gate cell is set precisely in manufacturing The reference voltage output itself is a buffered version of the floating gate voltage The resulting reference device has excellent characteristics that are unique in the industry very low temperature drift high initial accuracy and almost zero supply current Also the reference voltage itself is not limited by voltage bandgaps or zener settings so a wide range of reference voltages can be programmed (standard voltage settings are provided but customer-specific voltages are available)
The process used for these reference devices is a floating gate CMOS process and the amplifier circuitry uses CMOS transistors for amplifier and output transistor circuitry While providing excellent accuracy there are limitations in output noise level and load regulation due to the MOS device characteristics These limitations are addressed with circuit techniques discussed in other sections
Nanopower OperationReference devices achieve their highest accuracy when powered up continuously and after initial stabilization has taken place This drift can be eliminated by leaving the power on continuously
The ISL60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits The ISL60002 consumes extremely low supply current due to the proprietary FGA technology Supply current at room temperature is typically 350nA which is 1 to 2 orders of magnitude lower than competitive devices Application circuits using battery power benefit greatly from having an accurate stable reference that essentially presents no load to the battery
In particular battery powered data converter circuits that would normally require the entire circuit to be disabled when not in use can remain powered up between conversions as shown in
Figure 116 Data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty providing the highest accuracy and lowest possible long term drift
Other reference devices consuming higher supply currents need to be disabled in between conversions to conserve battery capacity Absolute accuracy suffers as the device is biased and requires time to settle to its final value or may not actually settle to a final value as power on time can be short
Board Mounting ConsiderationsFor applications requiring the highest accuracy board mounting location should be reviewed Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses It is normally best to place the device near the edge of a board or the shortest side as the axis of bending is most limited at that location Obviously mounting the device on flexprint or extremely thin PC material causes loss of reference accuracy

Board Assembly ConsiderationsFGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary Normal output voltage shifts of 100microV to 1mV can be expected with Pb-free reflow profiles Avoid excessive heat or extended exposure to high reflow or wave solder temperatures This can reduce device initial accuracy
Post-assembly X-ray inspection can also lead to permanent changes in device output voltage and should be minimized or avoided If X-ray inspection is required it is advisable to monitor the reference output voltage to verify excessive shift has not occurred If large amounts of shift are observed it is best to add an X-ray shield consisting of thin zinc (300microm) sheeting to allow clear imaging yet block X-ray energy that affects the FGA reference
Special Applications ConsiderationsIn addition to post-assembly examination there are also other X-ray sources that can affect the FGA reference long term accuracy Airport screening machines contain X-rays and have a cumulative effect on the voltage reference output accuracy Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift however if a product is expected to pass through that type of screening over 100 times consider shielding with copper or aluminum Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes therefore devices expected to go through those machines should definitely consider shielding Note that just two layers of 12 ounce copper planes reduce the received dose by over 90 The leadframe for the device that is on the bottom also provides similar shielding
If a device is expected to pass through luggage X-ray machines numerous times it is advised to mount a 2-layer (minimum) PC board on the top and along with a ground plane underneath effectively shields it from 50 to 100 passes through the machine Because these machines vary in X-ray dose delivered it is difficult to produce an accurate maximum pass recommendation
Noise Performance and ReductionThe output noise voltage in a 01Hz to 10Hz bandwidth is typically 30microVP-P Noise in the 10kHz to 1MHz bandwidth is approximately 400microVP-P with no capacitance on the output as shown in Figure 117 These noise measurements are made with a 2 decade bandpass filter made of a 1-pole high-pass filter with a corner frequency at 110 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency Figure 117 also shows the noise in the 10kHz to 1MHz band can be reduced to about 50microVP-P using a 0001microF capacitor on the output Noise in the 1kHz to 100kHz band can be further reduced using a 01microF capacitor on the output but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 01microF capacitance load For load capacitances above 0001microF the noise reduction network shown in Figure 118 is recommended This network reduces noise significantly over the full bandwidth As shown in Figure 117 noise is reduced to less than 40microVP-P from 1Hz to 1MHz using this network with a 001microF capacitor and a 2kΩ resistor in series with a 10microF capacitor

Turn-On TimeThe ISL60002 devices have ultra-low supply current and therefore the time to bias up internal circuitry to final values is longer than with higher power references Normal turn-on time is typically 4ms This is shown in Figure 119 Because devices can vary in supply current down to gt300nA turn-on time can last up to about 12ms Care should be taken in system design to include this delay before measurements or conversions are started
Temperature CoefficientThe limits stated for temperature coefficient (tempco) are governed by the method of measurement The overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures take the total variation (VHIGH ndash VLOW) and divide by the temperature extremes of measurement (THIGH ndash TLOW) The result is divided by the nominal reference voltage (at T = +25degC) and multiplied by 106 to yield ppmdegC This is the ldquoBoxrdquo method for specifying temperature coefficient
