Hi~

I saw the PFFB document about TPA324X & TPA325X,and how about TPA3221? Can we use the circuit as TPA3251?

Whether the feesback factor in the document is the best choice? Base on what ?Thanks!

Hi,

TPA3221 PFFB design is same as TPA325x. You can refer the Figure 2 of the PFFB document of the TPA325x.

Hi Yanming,

Thanks a lot for your reply. How about the TPA3223 and TPA3222? I can't find the corresponding value from TPA325X

Hi,

The TPA32XX series are same. The PFFB design is option for lower THD, lower out noise.

You can select to add or cancel the PFFB design up to your design requirement.

Regards,

Derek
