OP – AMP BASICS

IDEAL OP AMP

• Input impedance=Infinite• Output impedance = 0• Gain = Infinite• Bandwidth = infinite• Op amp neither sources nor sinks current

CONFIGURATIONS OF OP - AMPS

NEGATIVE FEEDBACK

OPEN – LOOP CONFIGURATION

POSITIVE FEEDBACK

NEGATIVE FEEDBACK

INVERTING AMPLIFIER CONFIGURATION

NON-INVERTING AMPLIFIER CONFIGURATION

LM741

IC 741 – PIN OUT

WHAT DOES ‘741’ IN IC 741 STAND FOR?

LET’S OBSERVE WHY…

SUMMER CIRCUIT

WORKING MODEL LM741- ON HOLD

OPEN LOOP CONFIGURATION

COMPARATOR

LM358 – PIN OUT

INTERNAL BLOCK DIAGRAM…

WHY SHOULD WE CARE ABOUT IT?

NEED FOR A TRIGGER

WHY 555?

LET’S SEE WHY…

555 PIN

OUT

3 MODES OF OPERATION

MONOSTABLE

ASTABLE

BISTABLE

MONOSTABLE STATE

HOW COULD WE USE 555 IN MONOSTABLE

STATE?

WORKING MODEL

ASTABLE STATE

HOW CAN WE USE ASTABLE MODE OF

OPERATION?

On hold….

THANK YOU! :D
