You can see from looking at the block diagram above that the isolation is transformer based, it’s quite remarkable that they can fit 5 transformers in such a small package. If you can’t attend the workshop the pcb files can be found on github and all the parts at Newark/Element14.
Newark/Element14 have an excellent video from Analog Devices embedded in their product web page for the ADUM3160/4160. I’ve embedded it below.
When: April 17th and 24th 7:00PM
