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.
