Other Parts Discussed in Thread: TPA6203A1, TPA6211A1
Hi,
We received inquiries from a customer about the POP noise of TPA6211A1-Q1 entering shutdown mode.
The lower Figures are the circuitry of their designed board and observed waveforms of it.
channel 1 : /SHUTDOWN
channel 2 : SPOUT-
channel 3 : SPOUT+
function 2 : (SPOUT+) - (SPOUT-)
Q1: Is the level of POP noise (function 2 waveform) at the falling edge of /SHUTDOWN signal as same as EVM?
Q2: Is there any way to reduce the POP noise?
Best regards,
Akio Ito
