The SSM2135 dual audio operational amplifier permits excel- and portable digital audio units, the SSM2135 can perform lent performance in portable or low power audio systems, with preamplification, headphone and speaker driving, and balanced an operating supply range of 4 V to 36 V or ±2 V to ±18 V. line driving and receiving. Additionally, the device is ideal for The unity-gain stable device has very low voltage noise of input signal conditioning in single-supply, Σ-Δ, analog-to- 5.2 nV/√Hz, and total harmonic distortion plus noise below digital converter subsystems such as the AD1877. The SSM2135 0.01% over normal signal levels and loads. Such characteristics makes an ideal single-supply stereo output amplifier for audio are enhanced by wide output swing and load drive capability. digital-to-analog converters (DACs) because of its low noise A unique output stage permits output swing approaching the and distortion. rail under moderate load conditions. Under severe loading, The SSM2135 is available in an 8-lead plastic SOIC package the SSM2135 still maintains a wide output swing with ultralow and is guaranteed for operation over the extended industrial distortion. Particularly well suited for computer audio systems temperature range of −40°C to +85°C.
