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 multimedia systems requiring mixing of multiple signals.
