Overview
The ADUM6411BRSZ is a quad-channel digital isolator produced by Analog Devices Inc., incorporating the company's iCoupler® technology. This component integrates an isolated dc-to-dc converter, known as isoPower®, which provides regulated, isolated power adjustable between 3.15 V and 5.25 V. This integration eliminates the need for separate isolated dc-to-dc converters in low-power, isolated designs. The ADUM6411BRSZ is designed to offer a compact, total isolation solution using chip-scale transformer technology for both logic signals and the dc-to-dc converter.
