GENERAL DESCRIPTION
The SSM2163 provides eight audio inputs, each of which can
be mixed under digital control to a stereo output. Each input
channel can be attenuated up to 63 dB in 1 dB intervals, plus
fully muted. Additionally, any input can be assigned to either or
both outputs. A standard 3-wire serial interface is employed,
plus a Data Out terminal to facilitate daisy chaining of multiple
mixer ICs. No external components are required for normal
operation.
Excellent audio performance is attained. The SSM2163 has a
signal-to-noise ratio of –82 dBu (0 dBu = 0.775 V rms), with
10 dBu of headroom resulting in total dynamic range of 92 dBu.
Total harmonic distortion plus noise is 0.007% at 1 kHz with all
levels set at unity gain.

The SSM2163 can be operated from single (+5 V to +14 V) or
dual ( 4 V to 7 V) supplies, and is housed in 28-pin plastic
DIP and SOIC packages.
The SSM2163 is an ideal companion product to the Analog
Devices family of stereo codecs in high performance multi-
media systems requiring mixing of multiple signals.
