APPLICATIONS INFORMATION

TSH22 IN COMPARATOR APPLICATIONThe TSH22 is a dual high performances opera-tional amplifier featuring speed of 30MHz and sin-gle supply operation from 3V to 30V.

Most of operational amplifiers are not suited forcomparator use because of low transition speed,output signal incompatible with standard logicslevel and mainly, phase inversion.

The phase inversion occures when a strong differ-ential signal is applied to the device inputs. Theoutput level is then inverted and shows a wronglogic state. TSH22 does not present this problem-atic behaviour.

Figure 1 : Basic comparator application

Displayed curves below show the device re-sponse in standard comparator configuration with-out external components.

Transition speed : Typical transition speed undera single 5V supply voltage is about 2µs from50mV overdrive. VOH min. is 3.7V and VOL max. is0.2V (2kΩ load) making it compatible with stan-dard logic families.

Figures 3 & 4 show output signal transition for a50mV and 250mV input signal overdrive respec-tively of 3µs and 1µs.

PHASE INVERSION

Figure 5 & 6 show the behaviour in follower stagewith saturation output of TSH22 versus 15MHzstandard operational amplifier.

At high differential input voltage, the TSH22 keepsthe right output level thanks to its specific inputstructures.

The advantage is obvious on the following figuresand can be also an advantage in linear use whensaturation might occure.
