UTC 3422 IN COMPARATOR APPLICATION
The UTC 3422 is a dual bipolar operational amplifier offering a single supply operation from 3V ~ 36V with very
good performances: medium speed (25MHz), unity gain stability and low noise.
Most of operational amplifiers are not suited for comparator use because of low transition speed, output signal
incompatible with standard logics level and mainly, phase inversion. The phase inversion occures when a strong
differential signal is applied to the device inputs. The output level is then inverted and shows a wrong logic state. The
UTC 3422 does not present this problematic behaviour.
Figure 1 shows basic comparator application. Figure 2 shows the curves of the device response in standard
comparator configuration without external components.
Transition speed : Typical transition speed under a single 5V supply voltage is about 2μs from 50mV overdrive.
VOH(MIN). is 3.7V and VOL(MAX). is 0.2V (2kΩ load) making it compatible with standard logic families.
Figure 3 shows output signal transition for a 50mV input signal overdrive respectively of 3μs.
Figure 4 shows output signal transition for a 250mV input signal overdrive respectively of 1μs.

PHASE INVERSION
The UTC 3422 keeps the right output level thanks to its specific input structures at high differential input voltage.
The advantage is obvious on the following figures and can be also an advantage in linear use when saturation might
occure.
Figure 5 shows the behaviour in follower stage with saturation output of UTC 3422.
Figure 6 shows the saturation behaviour with 15MHz standard operational amplifier.
