Overview
The ADuM1300CRWZ-RL, produced by Analog Devices Inc., is a triple-channel digital isolator based on the iCoupler® technology. This component combines high-speed CMOS and monolithic transformer technology to provide superior performance characteristics compared to traditional optocouplers. It eliminates the design difficulties associated with optocouplers, such as uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects. The ADuM1300CRWZ-RL operates with supply voltages ranging from 2.7 V to 5.5 V, enabling compatibility with lower voltage systems and voltage translation across the isolation barrier.
