I'd like to use ADM2582E isolating chip but without loading internal iCoupler. What is the absolute maximum ratings of the Visoin pin?
This is not a normal mode of operation. Can you describe in more detail what you are trying to do please (a block diagram may help).
The abs max rating of the Visoin pin (-0.3 to 6V) (input power to secondary side iCoupler signal isolation and RS-485 function) is a stress rating only and does not impart functional operation information… (which would be 3.0V to 3.6V for functional operation).
