1.9. U602 (WM8521H9GED/RV SOIC-14)
DESCRIPTION
The WM8521 is a 96kHz stereo DAC with an integrated output op-amp stage, designed to generate a 2.0Vrms output signal directly, so reducing external
component requirements in digital audio applications.
WM8521 comes into two variants WM8521HC and WM8521H9 which offers different line drive output capabilities. WM8521HC outputs 2Vrms at 12V
supply, while WM8521H9 outputs 2.0Vrms at 9V supply. WM8521HC/H9 are designed for cost sensitive consumer digital audio applications requiring
2Vrms line output.
A 24-bit multi-bit sigma delta DAC is used with oversampling digital interpolation filters. Digital audio input word lengths from 16-32 bits and sampling rates
from 8kHz to 96kHz are supported.
The audio interface supports I
2
S, Right Justified and DSP digital audio formats.
The devices are controlled via a hardware interface which provides access to features including de-emphasis, mute and data formats. These devices are
pin equivalent and are available in a 14-pin SOIC package.
