Hello support team,
I have a question regarding the power-up sequence of ADS8664.
Is there any regulation concerning the sequence at power on?
For example, which of AVDD and DVDD needs to be powered-up first?
Best regards,
M. Tachibana

Hello,
The power up sequence of the ADS8664 is not explicitly defined in the datasheet.
The datasheet references a TI Design that uses another SAR from the same family, TIDA-00164, and in this design the AVDD and DVDD supplies are tied together.
I recommend having AVDD and DVDD come on at the same time to avoid any power sequencing issues.
Please let me know if you have any follow-up questions.
Thanks,

Hello Kaczmarek-san,
If DVDD powers up earlier than AVDD, what kind of problems can be considered?
Could you teach me?
