General Description

The CS4270 is a high-performance, integrated audio

CODEC. The CS4270 performs stereo analog-to-digital

(A/D) and digital-to-analog (D/A) conversion of up to

24-bit serial values at sample rates up to 216 kHz.

Standard 50/15

µs de-emphasis is available for sam-

pling rates of 44.1 kHz for compatibility with digital audio

programs mastered using the 50/15

µs pre-emphasis

technique.

Integrated level translators allow easy interfacing be-

tween the CS4270 and other devices operating over a

wide range of logic levels.

Independently addressable high-pass filters are avail-

able for the right and left channel of the A/D. This allows

the A/D to be used in a wide variety of applications

where one audio channel and one DC measurement

channel is desired.

The CS4270’s wide dynamic range, negligible distor-

tion, and low noise make it ideal for applications such as

DVD-recorders, digital televisions, set top boxes, ef-

fects processors, and automotive audio systems.
