Determination of Input offset voltage, Input Bias current, Slew rate of Op-Amp

The Operational Amplifier (OPAMP) is a key building block in analog integrated circuit design. The OPAMP is composed by several transistors and passive elements (resistors and capacitors) and arranged such that its low frequency voltage gain is very high, the dc gain of the OPAMP-741 is around 10 5 V/V.

To summarize, the characteristics of an ideal op-amp are as follows:
•    Infinite bandwidth due to the ideal gain inside of the op-amp
•    Infinite open-loop gain A
•    Infinite or zero common-mode gain
•    Input impedance of an infinite value
•    Output impedance of zero

Apparatus Used:-

1)    Op-amp IC 741.
2)    DMM.
3)    Function Generator.
4)    CRO.
5)    Connecting wires.
6)    Power Supply.
