Electrical Engineering ⇒ Topic : Operational Amplifier
The term Operational Amplifier first appeared in 1947. The abbreviated form of Operational Amplifier is OP Amp. In earlier days, the major usage of OP Amp was in analogue simulations and in solutions of integro-differential equations. Nowadays, OP Amp has become a basic analogue building block of electronic functions performed in instrumentation, computation, and control.Basically it is a differential amplifier. Its main function is to amplify the difference between two input signals.
