WM8522

24-bit, 192kHz 6-Channel DAC with 1.7Vrms Line Driver

DESCRIPTION

FEATURES

•

6-Channel DAC with 1.7Vrms line driver from 5V analogue

supply

The WM8522 is a multi-channel audio DAC ideal for DVD

and surround sound processing applications for home hi-fi,

automotive and other audio visual equipment.

•

Audio performance

−

SNR 102dB (‘A’ weighted @ 48kHz)

THD -85dB (48kHz)

Three stereo 24-bit multi-bit sigma delta DACs are used

with oversampling digital interpolation filters. Digital audio

input word lengths from 16-32 bits and sampling rates from

8kHz to 192kHz are supported.

•

DAC sampling frequency: 8kHz – 192kHz

3-Wire SPI serial or hardware control interface

Programmable audio data interface modes

Each DAC channel has independent digital volume and

mute control, and provides 1.7Vrms line drive capability

from a 5V supply. This makes the device ideal for cost-

sensitive consumer applications requiring high line drive

audio outputs

−

I²S, left, right justified or DSP

16/20/24/32 bit word lengths

•

Three independent stereo DAC outputs with independent

digital volume controls

The audio data interface supports I²S, left justified, right

justified and DSP digital audio formats

•

Master or slave audio data interface

4.5V to 5.5V analogue, 2.7V to 3.6V digital supply

operation

The device is controlled via a 3 wire serial interface or

directly using the hardware interface. These interfaces

provide access to features including channel selection,

volume controls, mutes, de-emphasis and power

management facilities. The device is available in a 28-lead

SSOP.

•

Pin compatible with WM8766

28-lead SSOP package

APPLICATIONS

•

DVD Players

Surround Sound AV Processors and Hi-Fi systems

Automotive Audio
