iCoupler EMI mitigation

Hello T.Kamino,

We would recommend the newest triple channel device: ADuM131E1. It is pin-compatible with the ADuM1301, but offers improved radiated emissions performance, higher CMTI and noise immunity, and much lower propagation delay. It's also available in two package options: wide body SOIC (3.75 kVrms) and narrow body SOIC (3.0 kVrms), whereas the ADuM1301 is only available in the wide package with 2.5 kVrms rating. Your customer could likely use the narrow body package if the creepage requirements are met.

It may be that the ADuM131E would not require EMI mitigation depending on the data rate, but would certainly need less than the ADuM1301.

: can you help with the questions regarding AN-1109?
