Dual Single-Supply Audio Operational Amplifier

The SSM-2135 Dual Audio Operational Amplifier permits excelent performance in portable or low power Audio systems, with an operating supply range of +4V to +36V or +2V to 18V. The unity gain stable device has very low voltage noise of 4.7 nV/(root)Hz, and total harmonic distortion plus noise below 0.01% over normal signal levels and loads. Such characteristics are enhanced by wide output swing and load drive capability. A unique output stage permits output swing approaching the rail under moderate conditions. Under severe loading, the SSM-2135 still maintains a wide output swing with ultralow distortion.
Particularly well suited for computer Audio systems and portable digital Audio units, the SSM-2135 CAN perform preamplification, Headphone and speaker driving, and balanced line driving and receiving. Additionally, the device is ideal for input Signal Conditioning in single-supply sigma-delta Analog-to-digital converter subsystems such as the AD1878/AD1879.
The SSM-2135 is available in 8-pin plastic DIP and SOIC packages, and is guaranteed for operation over the extended industrial temperature range of -40C to +85C.
