| LESHAN RADIO COMPANY, LTD. General Description 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. The LR358/358C series are Compatible with Industry standard 358. The LR358/358C series are available in standard packages of DIP-8 and SOIC-8. Features Internally Frequency Compensation Large Voltage Gain Low Input Bias Current Low Input Offset Voltage Large Output Voltage Swing Applications Battery Charger Cordless Telephone Switching Power Supply SOIC-8 DIP-8 Figure 1.
