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. TSH22 does not present this problematic behaviour. Figure 1 : Basic comparator application 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 2s from 50mV overdrive. VOH min. is 3.7V and V OL max. is 0.2V (2k 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 3s and 1s. Figure 2 : Operating conditions +5V Vin+ TSH22 Vref 2kW Vout Figure 3 : Transition speed@ 50mV overdrive Figure 4 : Transition speed@ 250mV overdrive 5/11 TSH22 PHASE INVERSION At high differential input voltage, the TSH22 keeps the right output level thanks to its specific input structures. The advantage is obvious on the following figures and can be also an advantage in linear use when saturation might occure. Figure 5 : Behaviour with TSH22 Figure 5 & 6 show the behaviour in follower stage with saturation output of TSH22 versus 15MHz standard operational amplifier.
