WM8521

Stereo DAC with Integrated Output Stage

for 2Vrms LINE OUT

DESCRIPTION

FEATURES

•

Audio Performance

The WM8521 is a 192kHz 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.

DAC SNR 98dB (‘A’ weighted @ 48kHz)

THD -81dB (‘A’ weighted @ 48kHz)

•

DAC Sampling Frequency: 8kHz – 192kHz

Pin Selectable Audio Data Interface Format

- I²S, 16-bit Right Justified or 16bit DSP

2.0 Vrms output at 12V or 9V supply

7.6V to 13.2V Analogue, 2.7V to 3.6 Digital Supply

14-lead SOIC Package

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.

•

APPLICATIONS

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 192kHz are

supported.

•

Consumer digital audio applications requiring 2 Vrms output

- DVD Players

- Digital TV

- Digital Set Top Boxes

- A/V Receivers

The audio interface supports I²S, 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-lead SOIC package.
