Overview
The ADUM1400ARWZ-RL is a quad-channel digital isolator produced by Analog Devices Inc. It is based on Analog Devices' iCoupler® technology, which combines high-speed CMOS and monolithic transformer technology to provide reliable and high-speed data isolation. This component is designed to ensure dc correctness in the absence of input logic transitions and when power is not applied to one of the supplies, thanks to its patented refresh feature.
