The WM8722 is a high performance stereo DAC designed for audio applications such as digital TV and set top boxes. The WM8722 has two stereo analogue outputs, one at line level and one that includes a digitally controllable mute and attenuator function. An on-board tone generator can be routed through the line or variable outputs. WM8722 supports data input word lengths from 16-24 bits and sampling rates up to 96kHz.
The WM8722 is a high‑performance stereo DAC intended for digital TV, set‑top boxes and other audio applications. It provides a line‑level output and a variable‑level output with mute and attenuation, plus an on‑board tone generator that can be routed to either output.
The document includes a block diagram, pin configuration, electrical characteristics, recommended external components and mechanical dimensions, allowing designers to integrate the device into their systems.
