AD5686 output not updated.

Dear all.

I am using AD5686 DAC for audio output.

It is working properly.

However, in rare cases the DAC output is not updated and the output completely disappears.

It only happens occasionally(about once in 1 to 2 weeks) and I can’t reproduce the problem.

In my guess, I think that there is a possibility of deadlock due to accidental noise and crosstalk.

Have you ever encountered a similar problem?

Or is there a way to recover when the DAC deadlocks?


Any help will be appreciated.
