Overview
The ADuM1400WSRWZ is a quad-channel digital isolator produced by Analog Devices Inc., utilizing the company's proprietary iCoupler® technology. This component combines high-speed CMOS and monolithic air core transformer technology to provide superior performance characteristics compared to traditional optocoupler devices. The ADuM1400WSRWZ eliminates the need for external drivers and discrete components, reducing design complexity and power consumption. It operates 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.
