WebThe operational amplifier (op amp). (7) where A is the voltage gain of the op amp. Since the circuit amplifies the difference between the two input signals, it is referred to as a differential amplifier. Typical low-frequency voltage gains for a general-purpose op amp are 200,000–300,000 V/V. Weba Differential Amplifier A standard operational amplifier has two inputs, inverting and noninverting, we can also connect signals to both of these inputs at the same time producing another common type of operational amplifier circuit called a Differential Amplifier.
