Utilizing the circuit designs perfected for the quad operational amplifiers,
these dual operational amplifiers feature: 1) low power drain, 2) a common
mode input voltage range extending to ground/VEE, and 3) Single Supply or
Split Supply operation.
These amplifiers have several distinct advantages over standard
operational amplifier types in single supply applications. They can operate at
supply voltages as low as 3.0 V or as high as 36 V with quiescent currents
about one–fifth 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
The MC3458/3358 is made using two 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 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.
