Hi.
1) Is there any requirement on power rail sequencing for the 8V97051L?
2) Are any of the power rails extra sensitive to noise?
3) The datasheet states that all power rails "must have the same value as VDDA". How critical is this? Can the different rails vary from each other by let's say 50 mV?
Regards
Smurfigast,
1) No
2) Not overly sensitive, but like all electronics some care should be taken to reduce noise. The built-in LDO can deal with most of small noise issues.
3) It is best that they all match as this improves performance on the device. Some performace might be reduced with a 50mV difference on some of the power rails are not the closer say not more than 10mV difference.
