Overview
The ADUM2201ARWZ-RL is a dual-channel digital isolator produced by Analog Devices Inc., utilizing the company's proprietary iCoupler technology. This component combines high-speed CMOS and monolithic air core transformer technology to provide superior performance and reliability compared to traditional optocoupler devices. The ADUM2201ARWZ-RL is designed to eliminate the design difficulties associated with optocouplers, such as uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects. 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.
