Hello,
Nice to meet you all.
The AD7768-4 data sheet does not explain the power-up sequence (AVDD1, AVDD2, IOVDD).
However, the EVAL-AD7768-4FMCZ circuit uses the ADM1185 to perform the power-up sequence.
AVDD1,2->IOVDD->AMP_VDD
Does the ADD7768-4 require a a power-up sequence?
I would be glad if you could give me an answer.
Regards,
Naoya Takamura
