Product Number: Adau1701
Software Version: NA
I have a problem with the ADAU1701,
it is working on active Electrovoice
and FBT booths working in selfboot mode,
it starts working fine but suddenly it starts
to generate a noise and the audio fades,
the voltage on the FiltD pin increases
from 1.6 V to 2.7V, I have already changed the ADAU,
I have changed the capacitors of FiltD, FiltA, CM,
but the problem still continues,
I have 4 cards with the same problem and
I have not been able to solve them, can you help me.
I have found that in some cases instead of increasing
the voltage in FiltD it decreases and it is solved
by changing the capacitors but in this case it does
not decrease but instead increases and therefore the
dsp generates noise in the outputs and the audio
does not pass.
