Hi, i'm trying to design my own TPA3255 amplifier board, after seeing that most ones online are bad / terrible. One of those failed in front of my eyes for no apparent reason, while playing music well below the maximum power level of the IC (300W RMS x 2).
But i ran into a problem: i cannot understand how to feed the audio signal to the inputs of the tpa3255.
In the TPA3255 IC, there are input A, input B, input C and input D, but i dont know how to use them, i was expecting to find two simple inputs and a ground, like in the TPA3116D2.
But this one seems to be different.
Does anyone know how to use those inputs? Thanks in advance.

The first step to your own design is reading and understanding the data sheet of TPA3255.
This will answer your question.

Well, i tried... But i just cannot understand it. I'm just a hobbist, i can understand a lot but not everything.
It does not say a lot regarding the inputs. There is not even a full example schematic, it does not include this part of the circuit that i'm trying to understand...
Actually, this is the only part i wasn't able to understand.

So... There was this single ended to differential signal converter in the way. I just couldn't find that this was the thing i needed and how to make it. Thanks!
For the filter capacitor 10nF is good?
