WM9709

AC-link Interface Audio DAC

DESCRIPTION

FEATURES

The WM9709 is a low cost, high-quality stereo audio DAC.

It utilises the Intel specified AC-link audio interface protocol,

allowing a pair of audio output channels to be added to any

AC link compliant controller device at minimal board area

and external component cost.

•

20-Bit Stereo DAC

Audio Performance

−

102dB SNR (‘A’ weighted at 48kHz)

-95dB THD

•

Revision 1.03 or higher AC’97 AC-link interface support.

3.3V or mixed 3V digital, 5V analogue operation

20-Pin SSOP Package

The WM9709 device supports 48ks/s sample rates when

operated at the normal AC link rate. The WM9709 supports

a revision 1.03 AC ’97 AC-link interface, the device acting

as a master in normal operation.

Minimal external component cost

Support for surround and centre/LFE channels

APPLICATIONS

The ID pin can be used to select which data slots on the

AC-link are to be used as input to the DAC. This allows 3 x

WM9709 to be used with a single controller that supports 6

channel sound, to output surround sound audio signals.

When supporting surround, centre or LFE channels, the

WM9709 behaves as a slave device.

Motherboards

Custom sound applications

The WM9709 device is footprint compatible with the

WM9708 codec, allowing simple swapping between DAC

and full codec features on the same board. The WM9709 is

packaged in a 20-pin SSOP.
