Operational Amplifier

An operational amplifier also called op amp is an integrated circuit or analog circuit that takes input as a differential voltage and produces output as a single-ended voltage. It is an IC that can amplify weak electric signals.An op amp has one output pin and two input pins. The basic role of an opamp is to amplify the voltage difference between the two input voltages. It is also used in filtering or to perform mathematical operations or in signal conditioning.

Question

The op amp in the circuit shown is ideal.

1. Calculate vo if va=1 V and vb=0 V.

2. Repeat (a) for va=1 V and vb=2 V. 3. If va=1.5 V, specify the range of vb that avoids amplifier saturation.
