MC3403 datasheet, Pinout, application circuits

MC3403 datasheet, Pinout, application circuits Quad Low Power Operational Amplifiers using MC3403 The MC3403 is a low cost, quad operational amplifier with true differential inputs. The device has electrical characteristics similar to the popular MC1741C. However, the MC3403 has several distinct advantages over standard operational amplifier types in single supply applications. The quad amplifier can […]
