ADUM321N0WBRIZ-RL

Overview

The ADUM321N0WBRIZ-RL is a dual-channel digital isolator from Analog Devices, utilizing iCoupler technology for magnetic signal coupling. It features a 5700Vrms isolation rating and supports data rates up to 150Mbps with a maximum propagation delay of 10ns. The device operates on supply voltages ranging from 2.25V to 5.5V and includes fault-safe low output options. Packaged in an 8-SOIC (0.295 inch) format, it meets AEC-Q100 automotive qualification standards.

Feature Summary

• Integrates CMOS and monolithic air-core transformer technology for high-speed signal transmission across isolation barriers
• Provides robust noise immunity with high common-mode transient rejection capabilities typical of 180kV/µs
• Supports bidirectional voltage translation between 2.25V and 5.5V domains on both sides of the isolator

Applications

• Inverter control systems requiring galvanic isolation
• Industrial fieldbus network interfaces
• PWM controller signal isolation circuits
• General-purpose multi-channel isolation applications

Procurement Notes

Verify component authenticity through authorized distribution channels due to restricted availability status. Confirm that the specific suffix matches the required reel packaging configuration. Ensure compliance with AEC-Q100 automotive grade requirements if deploying in vehicle-related electronics. Cross-reference datasheet specifications against current production revisions to validate performance parameters.

Selection Notes

Select this component when high-speed data transfer exceeding 100Mbps is required alongside significant isolation voltage ratings. Consider the 10ns propagation delay for timing-sensitive applications. Evaluate the 2.25V minimum supply capability for compatibility with lower voltage logic families. Assess the SOIC package dimensions for PCB layout constraints compared to wider body variants.

Part Context

This part belongs to the ADuM320N/ADuM321N series of dual-channel digital isolators. It represents a variant optimized for higher data throughput compared to standard 1Mbps or 10Mbps models within the same family. The N0 suffix indicates a specific fault-safe output configuration distinct from other channel arrangements in the product line.
