Overview
The ADuM4165BRIZ, produced by Analog Devices Inc., is a USB 2.0 port isolator that utilizes Analog Devices' iCoupler® technology. This device is designed to provide galvanic isolation for USB 2.0 connections, supporting low, full, and high speed data rates of 1.5 Mbps, 12 Mbps, and 480 Mbps, respectively. The ADuM4165BRIZ combines isolator channels, USB transceivers, power and timing circuits, control logic, and internal terminations into a single 20-lead, wide-body, increased creepage SOIC_IC package. This integration makes it an ideal solution for applications requiring isolated USB ports.
