Description
The CS4225 is a single-chip, stereo analog-to-digital
and quad digital-to-analog converter using delta-sigma
conversion techniques. Applications include CD-quality
music, FM radio quality music, telephone-quality
speech. Four D/A converters make the CS4225 ideal for
surround sound and automotive applications.
The CS4225 is supplied in a 44-pin plastic package with
J-leads (PLCC) or as a die.
