Integrated Operational Amplifier Definition

The integrated operational amplifier is a three-stage direct-coupled amplifier with high gain (magnification of more than 100,000 times), high input impedance (above MQ level), and high common-mode rejection ratio. It is used for DC or AC amplification. The name comes from the early Its main purpose - to simulate various arithmetic circuits of computers (such as proportion, addition, subtraction, multiplication and division, integration, differentiation, etc.)
