Quizplus · Accepted Answer

A typical operational amplifier (op-amp) uses direct current (DC) coupling for its inputs and outputs, allowing it to amplify DC signals as well as alternating current (AC) signals. It usually requires two supply voltages, one positive and one negative, to operate correctly and to allow for the output to swing both positively and negatively from a zero reference point. Additionally, op-amps are characterized by their very high open-loop gain, which is the amplification provided without any feedback applied, often exceeding 100,000 times (100 dB).
