LM709 Operational Amplifier February 1995 LM709 Operational Amplifier General Description The LM709 series is a monolithic operational amplifier intended for general-purpose applications Operation is completely 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 Further 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 LM709 except that it is specified for operation from 0 C to a 70 C Connection Diagrams Metal Can Package Dual-In-Line Package TL H 11477 – 6 Order Number LM709CN-8
