DESCRIPTION
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 amplifiers 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.

For supply voltage less than ±15V, the absolute maximum input voltage is equal to the supply voltage.
Any of the amplifier outputs can be shorted to ground indefinitly; however more than one should not be simultaneously shorted as the maximum
junction will be exceeded.

CIRCUIT DESCRIPTION
The MC3403 is made using four internally compensated, two-stage operational amplifiers. The
first stage of each consists of differential input devices Q24 and Q22 with input buffer transistors
Q25 and Q21 and the differential to single ended
converter Q3 and Q4. The first stage performs not
only the first stage gain function but also performs
the level shifting and transonductance reduction
functions. By reducing the transconductance a
smaller compensation capacitor (only 8pF) can be
employed, thus saving chip area.
The transconductance reduction is accomplished
by splitting the collectors of Q24 and Q22. Another
feature of this input stage is that the input common-mode range can include the negative supply
fo ground, in single supply operation, without saturation either the input devices or the differential
to single-ended converter.
The second stage consists of a standard current
source load amplifier stage. The output stage is
unique because it allows the output to swing to
ground in single supply operation and yet does not
exhibit any crossover distortion in split supply operations. This is possible because class AB operation is utilized.
Each amplifier is biased from an internal voltage
regulator which has a low temperature coefficient
thus giving each amplifier good temperature characteristics as well as excellent power supply rejection.
