Operational Amplifiers

An operational amplifier (op-amp) is a high-gain direct-coupled multistage amplifier with the capability of amplifying signals ranging from DC (0 Hz) to several megahertz. Op-amps have five basic terminals: one for the positive supply, one for the negative supply, two for the input signals, and

    2. An operational amplifier (op-amp) is a high-gain direct-coupled multistage amplifier with the capability of amplifying signals ranging from DC (0 Hz) to several megahertz. Op-amps have five basic terminals: one for the positive supply, one for the negative supply, two for the input signals, and one for the output signal. The positive and negative power supplies connected to the op-amp allow the output voltage to swing positive or negative (with respect to ground).
