ADUM4160BRIZ-RL

Overview

The ADUM4160BRIZ-RL is a digital isolator based on iCoupler technology, designed for full and low-speed USB applications. It features magnetic coupling isolation with a 5000 Vrms insulation voltage and supports data rates up to 12 Mb/s. The device operates within a supply voltage range of 3.1 V to 5.5 V and includes bidirectional channels. Key electrical parameters include a propagation delay of 70 ns and a common-mode transient immunity of 25 kV/µs. It is housed in a 16-SOIC package and functions without an isolated power supply.

Feature Summary

• Integrates monolithic air core transformers for high-speed CMOS signal transmission
• Provides robust galvanic isolation for USB port protection
• Supports bidirectional data communication without isolated power requirements

Applications

• USB port isolation
• Full-speed and low-speed USB interface protection
• Digital isolation in industrial control systems

Procurement Notes

Verify the specific suffix RL indicates reel packaging when ordering. Confirm the SOIC-16 package dimensions match your PCB footprint requirements. Ensure the 5000 Vrms isolation rating meets your safety standards. Check humidity sensitivity levels for proper storage and handling procedures during assembly.

Selection Notes

Select this component for applications requiring reliable USB isolation with high common-mode transient immunity. Consider the 12 Mb/s data rate limit for protocol compatibility. Evaluate the 16-SOIC package size against available board space. Verify that the 3.1 V to 5.5 V supply range aligns with your system voltage rails.

Part Context

This part belongs to the ADuM4160 series of digital isolators from Analog Devices. It utilizes iCoupler technology to replace traditional optocouplers in USB interfaces. The series is designed to offer superior performance in terms of speed, reliability, and size compared to legacy isolation technologies.

Replacement Considerations

Direct substitutes may include other ADuM4160 variants with different packaging or temperature ratings. Verify pin compatibility and isolation voltage ratings before substitution. Consult official documentation for cross-reference lists.
