Have you any information concerning efficiency and power consumption changes
with temperature - -40C to +85C?

Are the efficiency figures for 5V in 5V out applicable to my application with
the Primary digital side supplied by 3v3.

 

From our characterization data, the ADuM347x efficiency from 5V in to 5Vout
over temperature has a minimum of about 68%. I checked with the designers about
applying these efficiency figures for VDDA supplied by 3.3V, and they said it
should be about the same.
