An operational amplifier (op-amp) is a type of electronic amplifier that amplifies the difference in voltage between its two input terminals. It typically has a high gain, high input impedance, low output impedance, and can be used in a wide variety of electronic circuits. The basic operation of an op-amp involves taking the voltage difference between the two input terminals (inverting and non-inverting), amplifying it by a factor determined by the op-amp's gain, and producing an output voltage based on this amplified difference. Op-amps are commonly used in amplifiers, filters, oscillators, and many other electronic circuits due to their versatility and reliability.
