What is a 741 op amp chip?
The 741 Op Amp IC is a monolithic integrated circuit, comprising of a general purpose Operational Amplifier. It was first manufactured by Fairchild semiconductors in the year 1963. The number 741 indicates that this operational amplifier IC has 7 functional pins, 4 pins capable of taking input and 1 output pin.
What is the purpose of operational amplifier?
An operational amplifier is an integrated circuit that can amplify weak electric signals. An operational amplifier has two input pins and one output pin. Its basic role is to amplify and output the voltage difference between the two input pins.
What are the various terminals of op amp 741 IC?
IC 741 has two terminals (Pin 1 and Pin 5) at input stage for the purpose where we can add external circuits to balance offset voltages. Offset null adjustment usually requires a potentiometer with its slider connected to the negative supply. Pin 4 is for negative power supply and pin 7 is for positive power supply.
Is op amp a transistor?
The standard 741 Op-amp circuit contains 20 transistors and 11 resistors. It starts with a differential input stage with a current mirror load. This is followed by an npn voltage amplification stage with an active output. A pnp emitter follower drives a push-pull emitter follower output stage.
