LM709

Operational Amplifier

General Description

The LM709series is a monolithic operational amplifier in-tended for general-purpose applications Operation is com-pletely specified over the range of voltages commonly used for these devices The design in addition to providing high gain minimizes both offset voltage and bias currents Fur-ther the class-B output stage gives a large output capability with minimum power drain

External components are used to frequency compensate the amplifier Although the unity-gain compensation network specified will make the amplifier unconditionally stable in all feedback configurations compensation can be tailored to optimize high-frequency performance for any gain setting The LM709C is the commercial-industrial version of the LM709 It is identical to the LM709except that it is specified for operation from 0 C to a 70 C
