WebAn op-amp is a high-gain differential amplifier module that forms the central component in a variety of useful, straightforward amplifier circuits. Designing with op-amps is far simpler than creating customized … WebThe op amp is designed to detect the difference in voltage applied at the input (the plus (v2) and the minus (v1) terminals, or pins 2 and 3 of the op amp package). The difference is also known as the differential input voltage. The output, then, is the difference sensed at the input multiplied by some value A - the open-loop gain.
