741 Operational Amplifier

uA741 Pin Diagram

PINs 2 and 3 of this operational amplifier IC we use for the input signal. We have to input the signal on PINs 2 and 3. Pin 2 is used as an (Inverting) pin and pin 3 is used as a (Non-Inverting) pin. PINs 1 and 5 are used for offset-null (Offset null).  And PIN 8 is not connected to anything.

If you separate this IC and make it on a PCB then you can see- 1. 20 transistors 2. 11 registers and 3. There is 1 ceramic capacitor

The UA741 IC is a single package operational amplifier that can be used in a wide range of applications, especially by students as well as engineers. Both are made of silicon and both can be used in general-purpose applications such as buffers, voltage followers, adders, amplifiers, comparators, etc.
