This document introduces the SSM2163 digital controlled 8 channel 2 channel audio mixer, including its features and characteristics, such as input and output, signal to noise ratio, distortion, applications, etc.
The SSM2163 is an 8-input, 2-output digitally controlled audio mixer designed for multimedia systems, broadcast equipment, and audio mixing consoles. It allows each of the eight inputs to be assigned to either or both stereo outputs with digital control. The device features voltage inputs and outputs, eliminating the need for external amplifiers, and provides 63 dB of attenuation in 1 dB steps plus a mute function for each channel.
The IC operates from single or dual power supplies and includes a standard 3-wire serial interface with a Data Out terminal for daisy-chaining multiple units. Key performance specifications include a signal-to-noise ratio of -82 dBu, 10 dBu of headroom, and a total harmonic distortion plus noise of 0.007% at unity gain. It is available in 28-pin Plastic DIP and SOIC packages.
