ADAU7002 overshoot?

Question asked by Silvan on Apr 30, 2013

I use the ADAU7002 to convert PDM signal to i2s.

When I turn on the power I get some kind of "overshoot" at the signal output for about 1 sec (image attached)

Is this normal behavior?

Can anyone explain the reason of that and how to prevent it?

Does it have to do with some kind of initialization of the ADAU7002  decimation filters?

Thank you!
