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.
We haven't received similar queries such as this.
Have you tried using HW and SW RESET functionality to recover?
When I tried to use HW and SW RESET, HW RESET worked well,
but SW RESET doesn't work. What is the cause of this?
However, I thought it was good to use HW RESET.
Thank you for your reply.
