General Description
The LR324 consists of four independent, high gain and
internally frequency compensated operational amplifi-
ers. It is specifically designed to operate from a single
power supply. Operation from split power supply is
also possible and the low power supply current drain is
independent of the magnitude of the power supply
voltages.
