good morning
I am making the printout for a volume control based on your indications, but I would like you to tell me how to do to prevent the CC from entering the PGA2311, and also what to do to adapt the impedance of my audio devices, because no one better than you can you solve the problem for me.
the first requires an impedance of 100k, the second of 22K and the third finally of 10k.
I thank you and I hope in your help a greeting to you all.

Perhaps you are referring to the input impedance of your amplifiers?
It is good practice to drive an amplifier with a low impedance source.
The PGA datasheet will recommend that you use a buffer stage (which will have a low output impedance) to drive any amplifier.
I hope I have the correct understanding of your question?
I totally didn't understand 'prevent the CC'.
