An operational amplifier (or an op-amp) is an integrated circuit (IC) which functions as a voltage amplifier. It has a differential input. That is, it has two inputs of opposite polarity. An op-amp has a single output and a very high gain, which means that the output signal is much higher than input signal. An op-amp is often represented in a circuit diagram with the following symbol:

Op-amps are among the most widely used electronic devices today, being used in a vast array of consumer, industrial, and scientific devices.For example ,it is used inpiezoelectric

transducers , can be used as charges amplifiers , it is used in electrocardiogram amplification and a lot many applications.
