Q
One customer is using our ADM2486 and noticed the Vdd2 can only be 5V, he just
want to know if 3.3v works or not.
He is evaluating the parts with Vdd1=Vdd2=3.3v and seems it works well.
A
Vdd1 is spec’d for both 3.3V & 5V supplies. It is possible that it would work
with Vdd2=3.3V but we do not guarantee the specifications at 3.3V and only
conduct our production testing to Vdd2 of 5V supply, so we cannot guarantee
operation at 3.3V.
The ADM2484E is the only signal isolated product with 3.3V Vdd2. This is a
500kbps part.
The ADM2482E has an integrated transformer driver, 16Mbps and 3.3V Vdd2 supply.
