Description

WM9704Q is a high quality audio codec compliant with the AC'97 Revision 2.1 specification. It performs full duplex 18-bit codec functions from 8 to 48k samples/s and offers excellent quality with high SNR. Features include 3D sound and line-level outputs. Support is also provided for variable sample rates and master/slave mode operation. Additionally the WM9704Q provides two proprietary modes:

4-channel quad mode enables two channels of ADC and DAC plus an additional two DAC channels as rear outputs.

6-channel mode configures the device to provide external support for two additional stereo outputs via the GPIO pins.

WM9704Q is interchangeable with AC'97 Codecs from Wolfson and other suppliers in the basic Revision 2.1 mode.

WM9704Q is fully operable with 3.3V or 5.0V or mixed 3.3/5.0V supplies and is packaged in an industry standard 48-pin TQFP package.
