Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. Either or both input voltages must not exceed the magnitude of VCC+ or VCC-.
3. Power dissipation must be considered to ensure maximum junction temperature (TJ) is not exceeded.

APPLICATIONS INFORMATION
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 l.
