we have made a nice design with the 1701.
Now we have been thinking about an wakeup via RCA, a kind of NF detection. Is the ADAU 1701 capable to detect NF input an generate an wakeup IO.?
We need an seperate 3,3V suply than to power off the main Amplifier via ADAU1701, I asume.
Do you have any hint for me.?
Thank you in advance
