Overview
The ADUM3441CRWZ is a four-channel digital isolator produced by Analog Devices Inc. It is based on the company's proprietary iCoupler technology, which enables high-speed data transfer across an isolation barrier. This component supports data rates up to 150 Mbps and is designed for applications requiring high voltage translation and low pulse width distortion. The ADUM3441CRWZ is particularly useful in scenarios where dc correctness is crucial, even in the absence of input logic transitions or during power-up/power-down conditions, thanks to its patented refresh feature.
