The SSM2135 Dual Audio Operational Amplifier permits excellent performance in portable or low power audio systems, with an operating supply range of +4 V to +36 V or ±2 V to ±18 V. The unity gain stable device has very low voltage noise of 4.7 nV/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 load conditions. Under severe loading, the SSM2135 still maintains a wide output swing with ultralow distortion.
Particularly well suited for computer audio systems and portable digital audio units, the SSM2135 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 analogto- digital converter subsystems such as the AD1878/AD1879.
The SSM2135 is available in 8-lead plastic DIP and SOIC packages, and is guaranteed for operation over the extended industrial temperature range of 40°C to +85°C.
