Operational Amplifiers and Linear Integrated Circuits: A Comprehensive Guide by Robert F. Coughlin and Frederick F. Driscoll**
An operational amplifier (op-amp) is a high-gain differential amplifier that amplifies the voltage difference between two input terminals. Op-amps are designed to be highly versatile, with a wide range of applications in linear and nonlinear circuits. They are commonly used in audio amplifiers, filters, and impedance matching circuits, among others. and impedance matching circuits
Linear integrated circuits (ICs) are a type of integrated circuit that processes continuous signals, as opposed to digital ICs, which process discrete signals. Linear ICs are used in a wide range of applications, including amplifiers, filters, and regulators. as opposed to digital ICs
