ADUM4160BRWZ

Overview

The ADUM4160BRWZ is a full/low speed USB digital isolator based on Analog Devices iCoupler technology. It provides bidirectional communication with 5000 Vrms isolation voltage and supports data rates up to 12 Mbps. The device features a maximum propagation delay of 70 ns and operates within a supply voltage range of 3.1 V to 5.5 V. It is housed in a 16-pin SOIC package and functions without an integrated isolated power supply.

Feature Summary

• Utilizes monolithic air core transformer technology for magnetic coupling
• Provides bidirectional signal transmission across the isolation barrier
• Designed specifically for USB port isolation applications

Applications

• Isolating USB peripherals in industrial equipment
• Creating isolation buffers for medical devices
• Implementing bus-powered cable isolators

Procurement Notes

Verify the specific suffix against official documentation, as variations may exist between tube and reel packaging formats. Confirm that the component meets required safety standards for the intended application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when high-speed USB communication requires galvanic isolation between host and peripheral systems. It is suitable for designs needing robust noise immunity in electrically noisy environments. Ensure the system architecture accommodates the lack of an integrated isolated power supply if separate power domains are utilized.

Part Context

This device belongs to the ADuM4160 series of digital isolators from Analog Devices. It leverages iCoupler technology to replace traditional optocouplers in USB interfaces. The series is engineered to address the growing demand for safe connections in industrial and medical sectors where hazardous voltages must be managed.
