Operational Amplifier (Op-Amp) is a high gain electronic voltage amplifier that can perform various mathematical operations like addition, subtraction, integration, and differentiation. It has two main inputs: inverting input (which is connected to the minus sign) and non-inverting input (which is connected to the plus sign), and one output. Op-Amps are widely used in electronic circuits such as filters, comparators, and voltage regulators.
