differential amplifier

Definitions

Electronics

  • An amplifier whose output signal is a function of the difference between its two input signals. For instance, the instantaneous output voltage of a differential amplifier being proportional to the instantaneous difference between its input voltages. Ideally, such an amplifier would have a zero output when both its inputs are identical. Also called difference amplifier, or differential input amplifier (1).
