Now we used TPA3116D2-Q1 as the power amplifier, and PBTL mode is used.
Pin 4/5 are the signals from Micro-p DAC output (tartget is 1khz/2khz nearly sine waveform).
Would you please check the min voltage range from Micro-p DAC can be detected for Pin 4/5 used (like if the sine wave from 0V~10mV?100mV?.. till 3.3V )?
Thanks!
