I understand that there is not power up or down sequence of AMUXVCC and AVCC.
Is it correct ?
It there is wrong with my understanding, please let me know your advice.
The process for the AD8195 uses dielectrically isolated devices which are immune to parasitic latchup. Therefore, there are no fundamental restrictions on the power-up and -down sequences. You should observe the restrictions in the Absolute Max Spec table, and not let the part experience a condition where one supply is applied and the other supply not-applied for a long duration.
I'll see what I can find out.
Thank you for the reply.
