I have two questions about quiescent supply current for ADuM240E/ADuM241E.
Q1. Are the test conditions correct ?
The quiescent supply currents are indicated in table1 and table3 which are printed in datasheet. Idd1 and Idd2 have two current…
I would recommend, specifically in harsh real world environments to have a external pull-up!!!
Ah, okay, I see. It turns out that digging through the digital isolators more thoroughly, I found a better one. The ADuM241 works as low as 1.8V, is 4-channel and can do 150 Mbps, so it's perfect.
Regarding the different ground pins on the ADuCM350…
