Description
The Audio Codec Board - PROTO is inexpensively priced development tool for WM8731 Audio Codec, ideal for use in embedded applications which requires audio playback. On-board module Audio Codec WM8731 provides stereo line and mono microphone level audio inputs. Also this module uses stereo 24-bit multi-bit sigma delta ADCs and DACs with oversampling digital interpolation and decimation filters. Stereo audio outputs are buffered for driving headphones from a programmable volume control, line level outputs are also provided along with anti-thump mute and power up/down circuitry. The device is controlled via a 2 or 3 wire serial interface.
