QThere is only a typical value provided in datasheet for isolated supply voltage
(3.3V). Is there a minimum and maximum spec/recommendation for Viso?
AWe don’t specify minimum and maximum specs for Viso, as Visoout is not intended
for powering external circuits, nor is Visoin intended to be supplied by
another power supply other than Visoout.
The tolerance for the 3.3V Viso output will be tighter than 5%, as shown in the
typical performance graph.
The ADM2682E/87E operation (including isolated supply) is tested and
characterized across all operating conditions, i.e. across Vcc supply and
ambient temperature range, as well as full RS-485 load and maximum data rate.
