Description
The CS4226 is a single-chip codec providing stereo an-
alog-to-digital and six digital-to-analog converters using
delta-sigma conversion techniques. This +5 V device
also contains volume control independently selectable
for each of the six D/A channels. An S/PDIF receiver is
included as a digital input channel. Applications include
Dolby Pro-logic, THX, DTS and Dolby Digital AC-3 home
theater systems, DSP based car audio systems, and
other multi-channel applications.
The CS4226 is packaged in a 44-pin plastic TQFP.
