This circuit is from the Motorola LinearDatabook of 1990. It shows how it uses the LF355, 356 and 357 operational capacitive loads. The power supply must be dual.
In the figure we have two circuits of limiters that provide the cut of the negative peaks of a...
This circuit triggers a load that depends on the characteristics of the transistor when we touch...
