Can anyone clarify what ADuM1401 side 1 drive value is? The data sheet tells only Absolute Maximum Ratings:
Average Output Current per Pin -18mA to + 18 mA
There are two ways to read this:
average/pin (3 outputs on this side) is max. 18 mA, total 54 mA OR
max. for each 18 mA in averaged in time.
Then there is a table of max. supply/side but this is much higher and contains dynamic part.
What will happen in time if one is loaded with 20 mA and other two have no load?
