Hi

Please let me know if there is "power-up-sequence" of AD5684R.

 

"Absolute max rate"would be say no "power up/down sequence" ,I think.

but the timing characteristic say 1.8<= VLOGIC <= VDD on a margin.

it's just test condition, I think, but.

 

These kind of devices need to fix the logic first before VDD supply, I think.

but POR circuit was design on VDD side.

Please tell me how to think.

 

Regards.
