i'm wondering if ADIS16448 has a protection circuit or not? i accidentally connect a 4.8v rather than 3.3v as power source
but i didn't have time to check wheather it is died or not.
The ADIS16448 does not have an over-voltage protection circuit. +4.8V is outside of the Absolute Maximum Ratings for the device, so damage is possible. I have not tried this myself so we look forward to your re-test to find out if your device survived.
REFERENCE: ADIS16448 Datasheet, Rev B, Table 3, Page 6
I hope that helps!
