Hi team,
If only VDD2 have 3.3V and VDD1 still have not voltage input.
Did the VOUTP and VOUTN have any risk in this condition ?
And how to let the VOUTP and VOUTN his output is 0V in this condition ?

Hi Eddie,
There are no power up sequencing requirements with the AMC1301. Please review section 9.3.2 and Figure 48 of the datasheet, VOUTp and VOUTn will assume the fail-safe state when VDD1 is not present.
