Hello! The TAS5722 is a mono device, so one output. What are you trying to design? If stereo please look at the TAS5766. Thanks, Jeff

Dear Jeff.
Thanks for you reply. Our customer need use one solution for mono and stereo application. They need use same PCB. So stereo mode is use two TAS5722L. I need to know if on mono mode and input is stereo I2S. How can I choose L or R output from TAS5722L? Thanks for help~

Hello! Maybe it would be easier to use one two-channel amp in your design, and then just configure for mono or stereo? I would recommend the TAS5760L, which is a newer much more configurable device.

Hello Andy! Do you have any other recommendation? Thanks, Jeff
