Overview
The ADUM4402ARWZ-RL is a 4-channel digital isolator produced by Analog Devices Inc., utilizing the company's iCoupler® technology. This component combines high-speed CMOS and monolithic air core transformer technology to provide superior performance compared to optocoupler devices and other integrated couplers. It offers four independent isolation channels, supporting various channel configurations and data rates. The isolator operates with supply voltages ranging from 3V to 5.5V, enabling compatibility with lower voltage systems and voltage translation across the isolation barrier. It also features a patented refresh mechanism to ensure DC correctness during power-up/power-down conditions and in the absence of input logic transitions.
