5 EVM Hardware Details
5.1 Analog InputsThe analog inputs to the EVM can be connected at the terminal blocks located on the left side of theboard (J6, J7, J9, and J10).
J6 (ADC IN1 channel) provides an optional fully-differential buffer that can be installed to evaluate theeffects of a buffered input channel. J10 (ADC IN4 channel) provides an optional buffer that can beinstalled to evaluate the effects of a single-ended buffered input channel.
WARNING
This EVM is not intended for connection to highvoltage. Do not connect inputs of this EVM to voltages higher than5 VAC to minimize shock hazard.
5.2 Digital InputsAccess the digital signals of the device via J3. This header allows for the connection to a logic analyzer orwhen the EVM is used in a stand-alone configuration for connections to the microprocessor ormicrocontroller.
If controlling the ADS131A04 with an external processor is desired, power down the onboardTM4C1294NCPDT by placing a jumper on JP1.
5.3 ClockBy default, a clock is supplied to the ADC via an external 16.384-MHz crystal.
To connect an external clock to the device, do the following:1. Remove R80 and R83, if they are populated.2. Connect the external clock to JP5 pin 1.
5.4 Mode PinsThe ADC Mx (mode) pins are controlled via S4 and JP5-7.
For operation with the EVM software, S4 should be switched to the up position (EVM Default), whichconnects the mode pins to default values that work with the EVM software.
NOTE: For the software to communicate with the hardware, S4 should be used in the EVM Defaultposition. The EVM may be removed and used separately with other modes of operation.
Switch S4 to the down position (Manual) for manual control of the mode pins and now JP5-7 controls themode pins. The mode pins are tri-state pins so JP5-7 have valid configuration in 1-2 (connected toIOVDD), 2-3 (connect to DGND), and open connection (floating).

5.4.1 Master and Slave ConfigurationS7 must be configured to agree with the Mx pin settings for the master or slave configuration of thehardware. By default, S7 is placed in the down position for slave mode operation. Switching S7 to upconfigures the hardware for master mode.
5.5 ADC ReferenceThe reference of the ADC can be provided via the reference and buffer on the EVM or from an externalsource.
To use the reference and buffer on the EVM, ensure that JP9 is installed. This is the default configurationof the hardware.
To use an external reference, remove JP9 and connect the external reference to JP9, pin 1.
5.6 ResetReset the ADC by pressing S6.

6 Power Supply Connections – EVM and ADC
6.1 Powering the EVMThe EVM is only powered by the USB connection at J1.
6.2 Powering the ADS131A04The ADS131A04 analog supply is provided by AVDD and AVSS connections. The ADC is designed to beoperated by either via single or bipolar supply.
6.2.1 Single-Supply ConfigurationTo connect the ADC in a single-supply configuration, install a jumper on JP11, pins 1-2. This connects 3.3V to AVDD and AGND to AVSS.
6.2.2 Bipolar Supply ConfigurationTo connect the ADC in a bipolar supply configuration, install a jumper on JP11, pin 2-3. This connects 2.5V to AVDD and –2.5 V to AVSS.
6.2.3 Charge Pump OperationTo use the charge pump on the ADS131A04, the device must be configured in single-supply operation byshorting pins 1-2 on JP11. Next, remove the jumper on JP8, if it is installed. Finally, correctly set theregisters in the ADS131A04 using the EVM software.
If the charge pump is unused, JP8 must be installed.
CAUTIONDo not operate the ADC in bipolar mode with the charge pump enabled. EnsureJP8 is removed before changing the JP11 connection to bipolar operation.
6.2.4 IOVDD SupplyInstalling JP10 allows the use of an external IOVDD voltage for the ADS131A04 which can be connectedat J11.
