Power-up sequence of AD5683R

Hi,

There are description about power-up sequence of AD5683R in the datasheet, P.26.

What happen If I couldn't keep the power-up sequence?

(The device will be broke or just the specification will change?)

Is there another rule about power supply , like ramp time or rule for  power-down?

Sorry for many questions.

Best regards,

Nom

    There is not restrictions in terms of ramp rate, as far is something "normal", we didnt test the part with a 10s ramp rate or non-montonic supply rate.

    As far as I remember, the only restriction is to connect GND before apply power to any pin.

    Obviously, we should recommend a supply to guarantee that under any condition the part will be stressed... If the delay between supplies is within ms, not major issue.
