WM8521 General Description
The WM8521 is a 96kHz stereo DAC with an integrated outputop-amp stage, designed to generate a 2.0Vrms output signaldirectly, so reducing external component requirements in digitalaudio applications.
WM8521 comes into two variants WM8521HC and WM8521H9which offers different line drive output capabilities. WM8521HCoutputs 2Vrms at 12V supply, while WM8521H9 outputs2.0Vrms at 9V supply. WM8521HC/H9 are designed for costsensitive consumer digital audio applications requiring 2Vrmsline output.
A 24-bit multi-bit sigma delta DAC is used with oversamplingdigital interpolation filters. Digital audio input word lengths from16-32 bits and sampling rates from 8kHz to 96kHz aresupported.
The audio interface supports I2S, Right Justified and DSP digitalaudio formats.
The devices are controlled via a hardware interface whichprovides access to features including de-emphasis, mute anddata formats. These devices are pin equivalent and areavailable in a 14-pin SOIC package.
