hi zhang

1.for this is a high power amplifier. not sure how much power be outputed in customer's design.

ferrite bead be used at output seems very rare for this kind of high power device. LC filter should be better.

2.single end input hasn't be verified by us. we do not recommend using like that.

tks

Hi Jesse,

We use the TPA3116D2 but we can't use the PBTL mode(BTL mode is normal), can you also review the schematic again and check if there are any error for this design, thanks.
