DESCRIPTION

TheTSH22 is a dual bipolar operational amplifier

offering a single supply operation from 3V to 30V

with very good performances : medium speed

(25MHz), unity gain stability and low noise.

The TSH22 is therefore an enhanced replacement

of standard dual operational amplifiers.

TSH22 APPLICATIONS INFORMATION TSH22 IN COMPARATOR APPLICATION The TSH22 is a dual high performances operational amplifier featuring speed of 30MHz and single supply operation from 3V to 30V. 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.

TSH22 PHASE INVERSION Figure 5 & 6 show the behaviour in follower stage with saturation output of TSH22 versus 15MHz standard operational amplifier. Figure 5 : Behaviour with TSH22 Figure 6 : Saturation behaviour with 15MHz standard operational amplifier Input & Ouput Voltages, Vid (V), Vo (V) At high differential input voltage, the TSH22 keeps the right output level thanks to its specific input structures.
