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.
