Overview
The MC3403DT, produced by STMicroelectronics, is a low-cost, quad operational amplifier with true differential inputs. It exhibits electrical characteristics similar to the popular UA741 but offers several distinct advantages, particularly in single supply applications. The device can operate with supply voltages ranging from 3V to 36V and has quiescent currents that are approximately one third of those associated with the UA741 on a per amplifier basis. The common-mode input range includes the negative supply, eliminating the need for external biasing components in many applications.
