ler via the AC’97 standard five wire interface. The controller

sends digital audio data to the HMP9701A to be converted to

analog stereo or monaural line output using two DACs.

We include an additional ADC to be used for Acoustic Echo

Canceling needed for video conferencing applications. This

ADC has a dedicated microphone input. It has the same high

quality performance as the stereo ADCs. The small 48 lead

TQFP (Thin 1.5mm and 7mm x 7mm footprint Quad Flat Pack-

age) makes it easy to locate the analog codec close to the ana-

log sources. Thus, reducing noise and lowering the cost of
