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.
