描述 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.
