Overview
The ADUM1300ARW from 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. By avoiding the use of LEDs and photodiodes, the ADUM1300ARW eliminates design difficulties associated with optocouplers, such as uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects. This isolator is designed to operate with supply voltages ranging from 2.7 V to 5.5 V, making it compatible with lower voltage systems and enabling voltage translation across the isolation barrier.
