General Description
The CS4272 is a high-performance, integrated audio
CODEC. The CS4272 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 192 kHz.
The D/A offers a volume control that operates with a
1 dB step size. It incorporates selectable soft ramp and
zero crossing transition functions to eliminate clicks and
pops.
The D/A’s integrated digital mixing functions allow a va-
riety of output configurations ranging from a channel
swap to a stereo-to-mono downmix.
Standard 50/15 µs de-emphasis is available for sam-
pling rates of 32, 44.1, and 48 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 CS4272 and other devices operating over a
wide range of logic levels.
An on-chip oscillator eliminates the need for an external
crystal oscillator circuit. This can reduce overall design
cost and conserve circuit board space. The CS4272 au-
tomatically uses the on-chip oscillator in the absence of
an applied master clock, making this feature easy to
use.
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 CS4272’s wide dynamic range, negligible distor-
tion, and low noise make it ideal for applications such as
A/V receivers, DVD-R, CD-R, digital mixing consoles,
effects processors, set-top box systems, and automo-
tive audio systems.
