Hi
I have two questions about AD7616.
Would you tell me the answer about these?
Question 1
Is there any problem if sequence is to power up VCC slightly first , followed by VDRIVE?
Question 2
Regarding to absolute maximum ratings of VDRIVE to AGND.
This rating is -0.3V to VCC + 0.3V, but recommended sequence is to power up VDRIVE first , followed by VCC.
Would you please explain these contents?
Best Regards,
Would you tell me answer about these?
We would like to know these information for new design ASAP.
Hi,
The AD7616 is robust to power sequence. But I would recommend following the one indicated in the abs/max rating.

Jonathan
Thank you for your support.
I understood this answer.
Best regards,
Please let me confirm again.
I changed the sequence to power up VCC first, then power up VDRIVE after 1 second.
Is there any problem with this sequence?
Hi ,
Do you have an update with regards to this issue?
If we follow the abs/max rating then we have to change the power-up sequence.
If So will the datasheet be changed in the future?
Thanking you
With best regards
Could you please update on this issue.
with best regards and wishes
