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
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.

Information furnished by Analog Devices is believed to be accurate and
reliable. However, no responsibility is assumed by Analog Devices for its
use, nor for any infringements of patents or other rights of third parties that
may result from its use. No license is granted by implication or otherwise
under any patent or patent rights of Analog Devices. Trademarks and
registered trademarks are the property of their respective companies.
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 condi-
tioning in single-supply, sigma-delta, analog-to-digital converter
subsystems such as the AD1878/AD1879.
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.
