DESCRIPTION

The MC3403 is a low-cost, quad operational ampli-

fier with true differential inputs. The device has elec-

trical characteristics similar to the popular UA741.

However the MC3403, has several distinct advan-

tages over standard operational amplifier types in

single supply applications. The quad amplifier can

operate at supply voltages as low as 3.0 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 in-

cludes the negative supply, thereby eliminating the

necessity for external biasing components in many

applications.
