ADUM4160BRWZ-RL

Overview

The ADUM4160BRWZ-RL is a full/low-speed USB digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It provides 5000Vrms isolation with a data rate of 12Mbps and 25kV/µs common-mode transient immunity (CMTI). The device features bidirectional channels, operates on a 3V to 5.5V supply, and exhibits a maximum propagation delay of 70ns. It is housed in a 16-SOIC package and supports an operating temperature range of -40°C to 105°C.

Feature Summary

• Integrates iCoupler magnetic coupling technology for robust signal transmission across isolation barriers.
• Supports high-speed bidirectional communication suitable for full and low-speed USB interfaces.
• Provides enhanced noise immunity through specified common-mode transient rejection capabilities.

Applications

• Isolating USB peripherals in industrial equipment
• Connecting medical devices requiring defibrillation-proof isolation
• PC peripheral interface isolation

Procurement Notes

Verify the specific suffix 'RL' corresponds to the reel packaging configuration required for your assembly line. Confirm that the 5000Vrms isolation rating aligns with your system's safety standards. Ensure the 16-SOIC footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring galvanic isolation for USB connections. It is appropriate for applications needing high CMTI to withstand noisy environments. Consider the 12Mbps data rate limit and 70ns delay when evaluating timing requirements for your specific bus protocol implementation.
