Operational amplifiers, commonly known as op-amps, are fundamental building blocks in the world of analog electronics. At a high level, an op-amp is a versatile integrated circuit (IC) designed to amplify voltage. It typically has two input terminals—an inverting input (-) and a non-inverting input (+)—and one output terminal. The core function of an op-amp is to amplify the voltage difference between these two inputs. This seemingly simple function allows op-amps to be used in an astonishingly wide array of applications, making them indispensable in modern electronic devices and systems.
