Part Number: AMC1301-Q1
Datasheet recommends 5V for VDD1 though the range is from 3 to 5.5V
I would like to know whether VDD1 and 2 can be given 3.3V from the same source or not. Appreciate your assistance.
Welcome to our e2e Forum! Great question here on the power supplies for the AMC1301-Q1! You certainly can supply power to the AMC1301 from the same source, the only issue there is that you may be defeating the isolation capability of the device. If you need to maintain the isolation, you could use a device like the SN6501 with a small signal transformer to generate an isolated 3.3 - 5V source for VDD1 from your VDD2 supply. That approach was used on the AMC1301EVM if you'd care to take a loot at the implementation.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
