Overview
The ADUM2200ARWZ is a 2-channel digital isolator produced by Analog Devices Inc., utilizing the proprietary iCoupler® technology. This component combines high-speed CMOS and monolithic air core transformer technology to provide superior isolation performance compared to traditional optocouplers. By eliminating the use of LEDs and photodiodes, the ADUM2200ARWZ avoids issues such as uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects commonly associated with optocouplers. This makes it an ideal solution for applications requiring reliable and high-speed digital isolation.
