Overview
The ADUM2402CRWZ-RL is a 4-channel digital isolator produced by Analog Devices Inc. It is based on Analog Devices' iCoupler technology, which provides high-speed data transfer and electrical isolation between two different voltage domains. This component is designed to operate with supply voltages ranging from 2.7 V to 5.5 V, making it compatible with a variety of systems and enabling voltage translation across the isolation barrier.
