Overview
The ADUM4400ARWZ-RL is a 4-channel digital isolator produced by Analog Devices, Inc. It is based on the iCoupler® technology, which combines high-speed CMOS and monolithic air core transformer technology. This component provides outstanding performance characteristics, including high data rates, low power consumption, and precise timing, making it superior to alternatives such as optocoupler devices and other integrated couplers. The ADUM4400ARWZ-RL operates with supply voltages ranging from 3.0 V to 5.5 V, enabling compatibility with lower voltage systems and voltage translation across the isolation barrier.
