GENERAL DESCRIPTION
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 analog-
to-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.
