Differential Amplifier Circuit. Such a circuit is very useful in instrumentation systems. The analysis of this circuit is essentially the same as that of an inverting amplifier except that the noninverting input of the op amp is at a voltage equal to a fraction of v 2 rather than being.

Characteristics of a differential. If all the resistor values are equal this amplifier will have a differential voltage gain of 1. A differential amplifier circuits can be of two types.
Such a circuit is very useful in instrumentation systems.
Differential amplifiers have high common mode rejection ratio cmrr and high input impedance. A differential amplifier basically takes in two voltage values finds the difference between these two values and amplifies it. It is used to provide high voltage gain and high common mode rejection ratio. It is virtually formed the differential amplifier of the input part of an operational amplifier.
