Overview
The ADuM1300ARWZ is a triple-channel digital isolator produced by Analog Devices Inc., utilizing the company's proprietary iCoupler® technology. This device combines high-speed CMOS and monolithic transformer technology to provide superior performance characteristics compared to traditional optocouplers. By eliminating the use of LEDs and photodiodes, the ADuM1300ARWZ avoids issues such as uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects commonly associated with optocouplers. This results in stable performance and reduced power consumption, with the device consuming one-tenth to one-sixth of the power of optocouplers at comparable signal data rates.
