Hi Jonathan,
First of all, we thank you a lot for your help.
We are not using a power sequencer so I suppose that the analog power is supplied first and then the digital power. We are going to measure the current of the power supplies to check that. What happens if we apply any voltage to the analog inputs before the analog power is established? Is this totally avoided with the Schottky diodes?
Regards,
