APPLICATIONS

Peak Detector

A3 acting as a comparator provides the logic drive for

operating SW1. The output of A2 is fed back to A3 and

compared to the analog input ein. If ein > eout the output of A3

is high keeping SW1 closed. This allows C1 to charge up to

the analog input voltage. When ein goes below eout A3 goes

negative, turning SW1 off. The system will therefore store the

most positive analog input experienced.
