Question
How do I connect PIN 7 (RCout) of ADuM5401 in a standalone application?
To Vdd1 or not connected ?
Answer
The RCout pin should be left as a no connect unless it is being sent to an RCin
pin of an ADuM520x or ADuM5000.
(RCout is Regulation Control Output. This pin is connected to the RCIN pin of a
slave isoPower device to allow the ADuM5401 to control the regulation of the
slave device).
