ADuM240x versus ADuM440x

Question asked by MarkS on Jul 29, 2013
Latest reply on Jul 30, 2013 by MarkS

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.
