I use two TPA3116 amps in my circuit. The circuit is near the same from datasheet. In my circuit I use a single supply +24V.
In the newest revision I use both in master mode without sinc mode (sinc isn't connected).
One of the two amps works good, but the other one with the same circuit blops and there is no signal from the input at the output.
I use the first part of the circuit on page 26 for both amps without sinc. I tried with sync, but it has no effect.
IN_N_RIGHT and IN_N_LEFT is connected to GND with C12 and C14.
IN_R_RIGHT is connected with the second amp (IN_R_RIGHT).
IN_P_LEFT is connected with the second amp (IN_P_LEFT) to.
