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, and Dolby Digital AC-3 home the-

ater systems, DSP based car audio systems, and other

multi-channel applications.

The CS4226 is packaged in a 44-pin plastic TQFP.
