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.
