The LM709 is an operational amplifier produced by National Semiconductor. Its features are high gain, low bias current, large output capability and a working temperature range of 0°C to 70°C.
The LM709 series is a monolithic operational amplifier intended for general-purpose applications. The design provides high gain while minimizing offset voltage and bias currents. It features a class-B output stage to deliver large output capability with minimum power drain.
External components are used to frequency compensate the amplifier, ensuring unconditional stability in all feedback configurations or allowing optimization for specific gain settings. The document covers absolute maximum ratings, operating conditions, electrical characteristics, schematic diagrams, typical applications circuits, and physical dimensions.
