Description

The IC 741 is a small chip. It comprises eight pins. 2, 3 and 6 numbered pins are most significant.
Pin 2 is inverting terminal.
Pin 3 is non-inverting terminal.
Pin 6 is output terminal.
IC 741 mainly performs mathematical operations like addition, subtraction, division, multiplication, integration, differentiation etc. IC 741 has three stages such as differential input, gain, and push-pull output.
Pin 1 and 5 are “offset null” or “balance” terminals.
The op amp is nothing but a differential amplifier. When we apply the same voltage at the inverting terminal (Pin 2) and the non-inverting terminal (Pin 3) there should not be any voltage at the output terminal (Pin 6). This condition is an ideal. Practically there is always a small voltage (offset voltage) appears at pin 6 even the voltage applied at pin 2 and 3 are exactly equal. Offset voltage appears at output because we can not make the parameters of transistors and value of biasing resistances of differential amplifier perfectly same.
