Overview
The ADUM241E1BRWZ is a quad-channel digital isolator produced by Analog Devices, Inc., utilizing the company's iCoupler® technology. This component combines high-speed, complementary metal-oxide semiconductor (CMOS), and monolithic air core transformer technology to provide superior performance compared to optocoupler devices and other integrated couplers. The device is designed for general-purpose multichannel isolation and offers compatibility with supply voltages ranging from 1.8V to 5V, enabling voltage translation across the isolation barrier. It ensures DC correctness even in the absence of input logic transitions and features two different fail-safe options.
