General Information

Circuit Information

The MC33201/2/4 family of operational amplifiers are

unique in their ability to swing rail–to–rail on both the input

and the output with a completely bipolar design. This offers

low noise, high output current capability and a wide common

mode input voltage range even with low supply voltages.

Operation is guaranteed over an extended temperature

range and at supply voltages of 2.0 V, 3.3 V and 5.0 V and

ground.

Since the common mode input voltage range extends from

VCC to VEE, it can be operated with either single or split

voltage supplies. The MC33201/2/4 are guaranteed not to

latch or phase reverse over the entire common mode range,

however, the inputs should not be allowed to exceed

maximum ratings.

Rail–to–rail performance is achieved at the input of the

amplifiers by using parallel NPN–PNP differential input

stages. When the inputs are within 800 mV of the negative

rail, the PNP stage is on. When the inputs are more than 800

mV greater than VEE, the NPN stage is on. This switching of

input pairs will cause a reversal of input bias currents (see

Figure 6). Also, slight differences in offset voltage may be

noted between the NPN and PNP pairs. Cross–coupling

techniques have been used to keep this change to a

minimum.

In addition to its rail–to–rail performance, the output stage

is current boosted to provide 80 mA of output current,

enabling the op amp to drive 600 Ω loads. Because of this

high output current capability, care should be taken not to

exceed the 150°C maximum junction temperature.
