GENERAL DESCRIPTION
The SSM2135 dual audio operational amplifier permits excel-
lent 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
5.2 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
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, Σ-Δ, analog-to-
digital converter subsystems such as the AD1877. The SSM2135
makes an ideal single-supply stereo output amplifier for audio
digital-to-analog converters (DACs) because of its low noise
and distortion.
The SSM2135 is available in an 8-lead plastic SOIC package
and is guaranteed for operation over the extended industrial
temperature range of −40°C to +85°C.
