ADS8910B: Power Sequence

Part Number: ADS8910B


I would like you to confirm power sequence(both power up and down) requirement for this device.

According to datasheet, I understood REFIN should be ramped up after AVDD reach expected voltage.

However, I'm not sure relationship between AVDD and DVDD.

If you have any requirement for power sequence except above, could you please let me know ?

Especially, I would like you to confirm about below.

* Sequence :

(I'm concerned about  which voltage is related to POR)

* Ramp up/down time for each voltage :

Best Regards,
