ADUM3160WBRWZ

Overview

The ADUM3160WBRWZ is a USB digital isolator utilizing iCoupler magnetic coupling technology. It provides 2500 Vrms isolation with a data rate of 12 Mbps and 25 kV/µs common-mode transient immunity. The device operates on a 3V to 5.5V supply, features bidirectional channels in a 16-SOIC package, and supports -40°C to +105°C temperatures.

Feature Summary

• Integrates high-speed CMOS with monolithic air core transformer technology for robust signal transmission
• Provides upstream-facing port isolation with transparent packet-by-packet direction detection
• Includes internal logic for controlling output buffer states and managing pull-up resistor connections

Applications

• Isolating low-speed and full-speed USB peripheral devices
• Microcontroller-based USB interface designs requiring galvanic isolation
• Systems needing simplified upstream port isolation for power management

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with required isolation voltage ratings and operating temperature ranges for your specific application environment before finalizing procurement decisions.

Selection Notes

Select this component when designing USB interfaces that require electrical isolation between host and peripheral. Consider its bidirectional nature and integrated control mechanisms for D+ and D- lines. Verify that the 12 Mbps data rate meets system requirements and that the 16-SOIC footprint fits the PCB layout constraints.

Part Context

Part of the ADUM3160 series within the iCoupler family. This series focuses on USB-specific isolation challenges by integrating bus state detection and direction control directly into the isolator, reducing external component count compared to generic digital isolators used in USB applications.

Replacement Considerations

Check Analog Devices datasheets for pin-compatible alternatives within the ADUM31xx series. Confirm that any substitute maintains the same USB protocol support, isolation voltage rating, and package dimensions.
