Hello, I would like to use the SSM6322 as stereo headphone driver with a balanced input and a unbalanced output (as shown in fig. 47 of the data sheet.I need to change the gain from 6dB to 20dB with an external command (using a cmos switch for changing the gain...). Is it possible to have the first differential amplifier with 6dB of gain and switching the gain of the buffer amplifier from 0dB to 14dB changing the feedback path from pin  VOUTx to pin VNFBx? The stability or the performances of the buffer could be compromised?

Thanks,

Enzo
