Overview
The ADUM226N1BRIZ, produced by Analog Devices Inc., is a dual-channel digital isolator that leverages 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. It is designed to offer high common-mode transient immunity, robustness to radiated and conducted noise, and low propagation delay, making it suitable for a wide range of applications requiring reliable and high-speed data isolation.
