WM9701A General Description
The WM9701A is a high-quality stereo audio codec compliant with the Intel AC'97 Rev 1.03 specification. Forming the analogue component PC audio solution, it performs full-duplex 18-bit codec functions at 48 ksamples/s and offers excellent audio quality with high SNR.
In addition, the WM9701A provides a comprehensive analogue mixer with 4 sets of stereo inputs, plus phone, 2 microphone,and PC-beep inputs. On-chip reference circuits generate the necessary bias voltages for the device, and a 5-pin digital bidirectional serial interface allows transfer of control data and DAC and ADC words to and from the AC'97 controller.The WM9701A is particularly suited to low power applications such as notebook PCs.
