ADN4654BRWZ

Overview

The ADN4654BRWZ is a dual-channel digital isolator utilizing magnetic coupling technology to provide high-speed signal transmission across isolation barriers. It supports data rates up to 1.25 Gb/s with low jitter, complying with TIA/EIA-644-A LVDS standards. The device operates on a single 2.5 V supply (range 2.375 V to 2.625 V) and features a propagation delay of 4 ns. It offers 5000 Vrms insulation voltage and common-mode transient immunity of 25 kV/µs. Housed in a 20-SOIC package, it functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates magnetic coupling for robust galvanic isolation between circuits
• Supports Gigabit LVDS signaling with low jitter performance
• Provides bidirectional or unidirectional channel configurations
• Operates reliably under high common-mode transient immunity conditions

Applications

• High-speed industrial communication interfaces requiring galvanic isolation
• Medical equipment signal isolation for patient safety compliance
• Automotive electronic control unit interconnects
• Test and measurement instrumentation data acquisition systems

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm the specific suffix BRWZ matches the required SOIC-20 package and tape/reel or tube quantity specifications. Check current availability status as supply may be limited. Ensure environmental compliance documentation aligns with project requirements before finalizing procurement orders.

Selection Notes

Select this component when high-speed LVDS isolation is required with minimal propagation delay. Verify that the 2.5 V supply voltage aligns with system power rails. Consider the 20-SOIC footprint for PCB layout constraints. Evaluate thermal dissipation capabilities given the maximum power dissipation rating. Ensure the isolation voltage rating meets the specific circuit safety requirements.

Part Context

This part belongs to the ADN4654 family of dual-channel LVDS digital isolators from Analog Devices. It complements other variants in the series offering different channel counts or insulation ratings. The family addresses the need for reliable high-speed data transfer in electrically noisy environments while maintaining strict isolation boundaries between ground domains.

Replacement Considerations

Direct substitutes include other ADN4654 variants with compatible pinouts and electrical characteristics. Verify equivalent isolation voltage and data rate specifications when considering alternative manufacturers. Ensure package dimensions match existing PCB footprints to avoid mechanical integration issues during replacement.
