I can't find the max input signal of TPA3125d2. My problem is that with ho input signals the amplifier switch off for a moment and then restart.
I am sorry I am not sure what is your problem? Could provide more details?

In reply to Peter Cao:
Hi, Michele Common mode voltage of TPA3125D2's LIN and RIN is 1.6V, so the max input signal is 3.2Vpp. It seems the device on your board has some fault (Over temperature shutdown or Over current protection shutdown), could you send your schematic to me?
In reply to michele fregoni:
Maybe the input signal has a spike at the start stage, this will cause a high output voltage spike (with small load) of TPA3125D2. However, for TPA3125D2, the Over current protection will Auto Recovery, so the AMP shutoff only for a moment.
