Overview
The ADUM140D0BRWZ-RL is a quad-channel digital isolator produced by Analog Devices Inc. This component utilizes Analog Devices' iCoupler® technology, which combines high-speed, complementary metal-oxide semiconductor (CMOS), and monolithic air core transformer technology. This design provides superior performance characteristics compared to optocoupler devices and other integrated couplers. The device is packaged in a 16-lead, RoHS compliant, SOIC package and is qualified for automotive applications. It operates with supply voltages ranging from 1.8 V to 5 V, enabling compatibility with lower voltage systems and voltage translation across the isolation barrier.
