ADUM3160BRWZ

Overview

The ADUM3160BRWZ is a USB digital isolator utilizing iCoupler technology, combining high-speed CMOS with monolithic air-core transformer technology. It provides 2500 Vrms isolation for USB 2.0 D+ and D- lines. The device supports data rates up to 12 Mbps with a common-mode transient immunity of 25 kV/µs. It operates on a single supply voltage ranging from 3V to 5.5V. The component features bidirectional channels within a 16-SOIC package and functions across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates high-speed CMOS logic with monolithic air-core transformer technology for robust signal transmission.
• Provides electrical isolation for USB differential data lines without requiring external magnetic components.
• Features edge-detection-based architecture that determines data direction on a packet basis for transparent operation.

Applications

• Isolating upstream ports in USB 2.0 host controllers
• Protecting microcontroller USB interfaces from peripheral faults
• Industrial systems requiring galvanic isolation for USB connectivity

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm packaging configuration. Ensure the revision level matches the design requirements. Confirm RoHS compliance status through the manufacturer's current certification records. Validate the 16-SOIC footprint dimensions against the latest datasheet drawings before finalizing procurement specifications.

Selection Notes

Select this component when designing USB interfaces that require galvanic isolation between host and device sides. It is suitable for applications needing protection against ground potential differences. Consider the 16-SOIC package size for space-constrained PCB layouts. Verify that the required data rate does not exceed the specified maximum limit for reliable communication performance.

Part Context

This part belongs to the ADuM3160 series of USB port isolators. It is designed specifically for full-speed and low-speed USB applications. The technology leverages silicon isolation barriers instead of traditional optocouplers or transformers. This approach offers improved reliability and smaller form factors compared to legacy isolation methods.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADuM family. Verify if updated revisions offer enhanced performance metrics. Ensure any substitute maintains the same isolation voltage rating and package type. Confirm compatibility with existing USB protocol implementations before switching components.
