What is Difference Amplifier?

A difference amplifier or differential amplifier amplifies the difference between the two input signals. An operational amplifier is a difference amplifier; it has an inverting input and a non-inverting input. But the open-loop voltage gain of an operational amplifier is too high (ideally infinite), to be used without a feedback connection.
