Description

The CS4272-CZZ is a high-performance, integrated audio CODEC designed for stereo analog-to-digital (A/D) and digital-to-analog (D/A) conversion. It supports up to 24-bit serial values at sample rates of up to 192 kHz. The D/A offers a volume control with a 1 dB step size and features selectable soft ramp and zero crossing transition functions to eliminate clicks and pops. The CS4272-CZZ also includes digital mixing functions for various output configurations and supports standard 50/15 µs de-emphasis for sampling rates of 32, 44.1, and 48 kHz.
