Overview
The ADUM2401CRWZ-RL is a 4-channel digital isolator produced by Analog Devices Inc., utilizing the company's proprietary iCoupler® technology. This device is designed to provide high-speed, low-power isolation for digital signals, making it suitable for a wide range of applications that require reliable and efficient signal isolation.
The ADUM2401CRWZ-RL operates with supply voltages ranging from 2.7 V to 5.5 V on both sides, enabling compatibility with lower voltage systems and facilitating voltage translation across the isolation barrier. It features a patented refresh mechanism to ensure DC correctness even in the absence of input logic transitions and during power-up/power-down conditions.
