We're using ADuM4400 series devices in our designs, but note the existence of the very similarly specified ADuM2400 series in the catalog. It seems that ADuM240x devices use a bit less current and have TUV60950 and TUV61010 Reinforced qualifications as extra certifications. The two series seem to cost the same.
Are there differences between ADuM240x and ADuM440x I have not discerned?
Is there any reason to prefer ADuM440x over ADuM240x, as given the latter's lower power consumption, I would otherwise select it.
Is ADuM240x newer and therefore to be preferred for new designs with anticipated long lifetimes?
Thanks for your help with this.
