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 sup-
ply 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 pack-
ages 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
