ADUM4402BRWZ

Overview

The ADUM4402BRWZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 5000 Vrms isolation voltage with enhanced ESD protection. The device supports data rates up to 90 Mb/s and operates on a single supply voltage ranging from 2.7 V to 5.5 V. Key electrical parameters include a propagation delay of 32 ns, rise and fall times of 3 ns, and a common-mode transient immunity of 25 kV/µs. It functions in unidirectional mode within an SOIC-16 package.

Feature Summary

• Integrates four independent channels for high-density signal isolation
• Employs monolithic air core transformer technology for magnetic coupling
• Provides enhanced electrostatic discharge protection capabilities
• Supports wide operating temperature ranges for industrial applications

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering and energy management circuits
• Automotive electronics interfaces

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SOIC-16 configuration. Confirm availability status through authorized distributors as supply constraints may apply to this component series.

Selection Notes

Select this component when four isolated channels are required within a compact footprint. Consider the 90 Mb/s data rate limit for high-speed communication needs. Evaluate the 5000 Vrms isolation rating against system safety requirements. Compare power consumption metrics if battery-operated designs are involved.

Part Context

This part belongs to the ADuM440x family of quad-channel digital isolators. It shares architectural similarities with other members like the ADUM4401 but differs in channel count or speed characteristics. The family utilizes CMOS technology integrated with transformer-based isolation for robust performance.

Replacement Considerations

Cross-reference with ADUM4402ARWZ for alternative speed grades within the same package. Verify pinout compatibility before substituting with other quad-channel isolators from different manufacturers.
