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 variety of output configurations ranging from a channel swap to a stereo-to-mono downmix.

Standard 50/15 µs de-emphasis is available for sampling rates of 32, 44.1, and 48 kHz for compatibility with digital audio programs mastered using the 50/15 µs pre-emphasis technique.
