HIGH PERFORMANCE DUAL BIPOLAR OPERATINAL AMPLIFIER

UTC 3422 LINEAR INTEGRATED CIRCUIT HIGH PERFORMANCE DUAL BIPOLAR OPERATINAL AMPLIFIER DESCRIPTION The UTC 3422 is a dual bipolar operational amplifier offering a single supply operation from 3V ~ 30V with very good performances: medium speed (25MHz), unity gain stability and low noise. The UTC 3422 is therefore an enhanced replacement of standard dual operational amplifiers.

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. Displayed curves below show 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. Figures 3 & 4 show output signal transition for a 50mV and 250mV input signal overdrive respectively of 3μs and 1μs.

The advantage is obvious on the following figures and can be also an advantage in linear use when saturation might occure.
