Operational Amplifier
An operational amplifier, often abbreviated as op-amp, is a versatile electronic component used to amplify voltage signals. It typically has two input terminals, called the inverting and non-inverting inputs, and one output terminal. Op-amps can perform various mathematical operations, such as addition, subtraction, integration, and differentiation, making them essential in analog circuits.
Op-amps are commonly found in applications like signal conditioning, filtering, and feedback control systems. They are characterized by high input impedance, low output impedance, and a high gain, which allows them to effectively process weak signals. Their flexibility and functionality make them a fundamental building block in modern electronics.
