ON MC3403P Quad differential input operational amplifier Datasheet

Order this document by MC3403/D
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
5.0 V/DIV
Inverter Pulse Response
20 µs/DIV
The MC3403/3303 is made using four internally
compensated, two–stage 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 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 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.
