TLV5614: AVDD and DVDD requirement when in Power Down (PD)

Nathan Coonrod
Prodigy 10 points
Part Number: TLV5614
Sheet 5 of the TLV5614 datasheet specifies that AVDD and DVDD cannot be more than +/- 2.8V apart. Does this hold true when PD is held low?
Specific application, AVDD (5V) is sequenced earlier than DVDD (3V3) and there may be up to a 5.25V difference between the two rails indefinitely. PD is tied to DVDD (3V3).
The datasheet does not specify sequencing requirements, or considerations for when PD is low, can you clarify if the above implementation meets the device requirements?

    Hi Nathan,

    Welcome to E2E and thank you for your query. As the ABS max ratings specify the AVDD and DVDD cannot be apart by +/-2.8V, this applies during power supply ramp-up as well. However, I am not able to understand your reference to PD.

    As PD is a digital signal, it won't have any implication on power supplies.
