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 bi-

directional 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.
