The CS4216 is an MwaveTM
audio codec.
The CS4216 Stereo Audio Codec is a monolithic
CMOS device for computer multimedia, automotive,
and portable audio applications. It performs A/D and
D/A conversion, filtering, and level setting, creating 4
audio inputs and 2 audio outputs for a digital computer
system. The digital interfaces of left and right channels
are multiplexed into a single serial data bus with word
rates up to 50 kHz per channel. Up to 4 CS4216 devices can be attached to a single hardware bus.
Both the ADCs and the DACs use delta-sigma modulation with 64X oversampling. The ADCs include a digital
decimation filter which eliminates the need for external
anti-aliasing filters. The DACs include output smoothing
filters on-chip.
