Overview
The ADUM240E0WBRWZ-RL is a 4-channel digital isolator produced by Analog Devices Inc., utilizing the company's proprietary iCoupler® technology. This component is designed to provide high-speed, reliable isolation between different voltage domains, making it suitable for a variety of applications that require robust signal isolation and voltage translation.
The ADUM240E0WBRWZ-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 low propagation delay, tight channel-to-channel matching, and high common-mode transient immunity (CMTI) of up to 100 kV/μs.
