Our customer asks below question about ADuM140E because he will set enable pin to OPEN .
Please let me know your advice.
Datasheet describes that EN pin of ADuM140E can be opne.
Does this contain internal pull-up resistor ?
If so, could you teach me resistor value of pull-up ?
Actually the pull-up function is not realized by resistor but a weak current source. Its typical value is 3uA when EN is tied to its reference ground. we would suggest to connect it to VDD if the application is noisy.
