5 APPLICATIONS INFORMATION TSH24 IN COMPARATOR APPLICATION The TSH24 is a quad high performances operational amplifier featuring speed of 3MHz and single supply operation from 3V to 3V. 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 TSH24 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 2µs from 5mV overdrive. V OH min. is 3.7V and V OL max. is.2v (2kΩ load) making it compatible with standard logic families. Figures 3 & 4 show output signal transition for a 5mV and 25mV input signal overdrive respectively of 3µs and 1µs. Figure 2 : Operating conditions Figure 3 : Transition speed@ 5mV overdrive Figure 4 : Transition speed@ 25mV overdrive 5/11

6 PHASE INVERSION At high differential input voltage, the TSH24 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 TSH24 Figure 5 & 6 show the behaviour in follower stage with saturation output of TSH24 versus MHz standard operational amplifier.
