Overview
The ADuM1300BRWZ-RL is a triple-channel digital isolator produced by Analog Devices Inc., leveraging the company's iCoupler® technology. This component combines high-speed CMOS and monolithic transformer technology to provide superior performance characteristics compared to traditional optocouplers. It eliminates the use of LEDs and photodiodes, thereby avoiding issues such as uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects. The ADuM1300BRWZ-RL is designed to operate with supply voltages ranging from 2.7 V to 5.5 V on both sides, enabling compatibility with lower voltage systems and voltage translation across the isolation barrier.
