I already know ADuM5020/5028 is low EMI isoPower.
Do you have low EMI isoPower include 4 channel isolator?
If the product has not yet been released, is it possible to arrange a PRE data sheet and sample?
If you have difficulty replying here, you can email us directly.
There is an ADuM542x series nearing release. I don't know the final schedule, so it would be best to work with your local sales representative for a preliminary data sheet and samples.
Thank you for your answer.
I will contact ADKK sales.
