AD1939

Question

I have read the data manual for AD1939, and the sampling rate can be set to 192khz. I see that the dynamic collection range is from 20Hz to 20KHZ. 
 So the question I raised is, can we capture audio from 20HZ to 80Khz? This is crucial for our chip selection, and we hope to receive your feedback in a timely manner. Thank you！！！

You can sample 80kHz signal with it. But the problem is, there are only 2+ points per cycle given that the sampling rate is only 2.x times of signal frequency.)

These two have 768K sampling rate.
