Overview
The ADUM3440CRWZ is a quad-channel digital isolator produced by Analog Devices Inc. This component utilizes Analog Devices' iCoupler technology, which supports data rates up to 150 Mbps and provides high voltage translation functionality across the isolation barrier. The ADUM3440CRWZ is designed to ensure dc correctness in the absence of input logic transitions and during power-up/power-down conditions, thanks to its patented refresh feature. It is particularly suited for applications requiring high signal integrity and insulation, such as industrial automation, medical devices, and automotive systems.
