  • RE: TPA3244: mute function

    Hello Connie, That external circuit would not work as the internal pin is different, so it would not work. The difference between cmute and reset is that while they both initiate a ramp down sequence of the outputs, and the output FETs go into a Hi…

  • TPA3244: amplifier reset when i touch pins

    Part Number: TPA3244 We designed amplifier board ( in single pcb there are 3 amplifier units ) using TPA3244. It work only for 1-3 minutes Fault LED light up and amplifier stop working. ICs are getting hot. What is strange is when I touch the top left…

  • RE: TPA3244: After measureing on outputs is nothing (AC or DC) on OUT pin, and on BST is about 12VDC. So if is possible to figure it out.

    Hi, Matej. Can you observe the RESET, INPUTA, INPUTB, OUTA(OUTB) waveform at the same time, and post the waveform for us to have a further analyze? Best regards. Wei Qiu.
