Dears Sirs, I have a problem with TPA3123D2 amplifier. It worked ok, but at this moment when I rise input signal level, the output is cut-off, current consumption latch in 170mA and the chip start hot.
I thought the speakers was demaged because if speakers are desconected it does not happen, but I has changed speakers and the situation is the same...
My circuit is very similar to descrived on "TPA3123D2EVM - User Guide" document.
I am desoriented... I has chequed the power suply, and it's ok.
Can any help my and suggest some measurement to confirm if I need replace TPA3123D or other asociated component?
Thanks in advance.
Ezequiel.-
