ADUM4402BRWZ-RL

Overview

The ADUM4402BRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler technology. It features four independent channels with unidirectional signal transmission. The device operates on a single power supply ranging from 2.7 V to 5.5 V. It provides an isolation voltage of 5000 VRMS and supports data rates up to 90 Mb/s. The component is housed in a 16-pin SOIC package.

Feature Summary

• Integrates four isolated channels within a single compact package
• Employs monolithic air core transformer technology for magnetic coupling
• Provides enhanced electrostatic discharge protection capabilities
• Supports high-speed digital signal transmission across isolation barriers

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering applications with high voltage separation
• Inverter drives and motor control circuits

Procurement Notes

Verify the specific suffix RL indicates reel packaging configuration. Confirm the BRWZ designation matches the required temperature range and package variant. Ensure compatibility with existing board layouts for the 16-SOIC footprint. Check current availability status as distribution may be limited or subject to allocation constraints.

Selection Notes

Select this component when four isolated channels are required in a single package. Consider the 5000 VRMS rating for high-voltage isolation needs. Evaluate the 90 Mb/s data rate against system timing requirements. Verify that the unidirectional channel configuration aligns with the signal flow direction of the application design.

Part Context

This part belongs to the ADuM440x series of quad-channel digital isolators. It represents a solution for replacing traditional optocouplers in space-constrained designs. The series offers improved performance metrics compared to legacy isolation technologies. It is designed for applications demanding high reliability and long-term stability.

Replacement Considerations

Direct substitutes include other quad-channel isolators from the same manufacturer family. Cross-reference pinouts and electrical specifications before substitution. Verify isolation voltage ratings match or exceed original requirements. Ensure package dimensions are compatible with existing PCB footprints.
