This circuit was found in Ferranti's 1967 documentation. The circuit drives a 40 V relay, but it can be adapted to operate with sensitive lower voltage relays.
This circuit amplifies the signals of an operational amplifier with output values that depend on...
We give in the figure a different application of 4013, which can also be used as monostable. In common...
