The MC3403 is a low-cost, quad operational amplifier with true differential inputs. The device has electrical characteristics similar to the popular UA741. However, the MC3403 has several distinct advantages over standard operational amplifier types in single supply applications. The quad amplifier can operate at supply voltage as low as 3 Volts or as high as 36 volts with quiescent currents about one third of those associated with the UA741 (on a per amplifier basis). The common-mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications.
This document is a datasheet for the MC3303, MC3403, and MC3503 series of low power quad bipolar operational amplifiers. These devices feature short-circuit protected outputs, a Class AB output stage for minimal crossover distortion, and support for both single and dual supply operation. The MC3403 is highlighted as a low-cost alternative to the popular UA741 with similar performance characteristics.
