Overview
The ADUM2401BRWZ-RL is a quad-channel digital isolator produced by Analog Devices Inc. This component utilizes Analog Devices' iCoupler® technology, which combines high-speed CMOS and monolithic air core transformer technology to provide superior performance characteristics compared to traditional optocoupler devices. The ADUM2401BRWZ-RL is designed to operate with supply voltages ranging from 2.7 V to 5.5 V, making it compatible with a wide range of voltage systems and enabling voltage translation across the isolation barrier.
