Dual, Low Power
Operational Amplifiers
Utilizing the circuit designs perfected for the quad operational
amplifiers, these dual operational amplifiers feature: low power drain,
a common mode input voltage range extending to ground/VEE, and
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.
•Short Circuit Protected Outputs
•True Differential Input Stage
•Single Supply Operation: 3.0 V to 36 V
•Low Input Bias Currents
•Internally Compensated
•Common Mode Range Extends to Negative Supply
•Class AB Output Stage for Minimum Crossover Distortion

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.
