WM9709 General Description

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.

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.

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.

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.
