LRC LR358

LESHAN RADIO COMPANY, LTD.
General Description
Features
The LR358/358C consists of two independent, high
gain and internally frequency compensated operational
amplifiers, 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.
