MC3403, MC3303
Single Supply Quad
Operational Amplifiers
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 operate at supply voltages as low
as 3.0 V or as high as 36 V with quiescent currents about one third of
those associated with the MC1741C (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. The output voltage range also includes the negative
power supply voltage.

CIRCUIT DESCRIPTION
Figure 2. Inverter Pulse Response
20
s/DIV
5.0 V/DIV
The MC3403/3303 is made using four internally
compensated, twostage operational amplifiers. The first
stage of each consists of differential input device 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 transconductance reduction
functions. By reducing the transconductance, a smaller
compensation capacitor (only 5.0 pF) 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 or ground, in
single supply operation, without saturating either the input
devices or the differential to singleended 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 operation.
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.
