ADUM320N0WBRIZ-RL

Overview

The ADUM320N0WBRIZ-RL is a dual-channel digital isolator from Analog Devices, utilizing iCoupler technology. It features unidirectional data transmission with a maximum data rate of 150 Mb/s and a typical propagation delay of 6.2 ns (max 10 ns). The device operates on supply voltages ranging from 2.25 V to 5.5 V, consuming approximately 3.1 mA of quiescent current. It provides 5700 VRMS isolation voltage and supports an operating temperature range of -40°C to +125°C. Packaged in an 8-SOIC wide body format, it includes AEC-Q100 qualification for automotive applications.

Feature Summary

• Integrates CMOS logic with monolithic air-core transformer technology for robust signal isolation
• Provides high common-mode transient immunity to suppress radiated and conducted noise
• Supports level shifting between different voltage domains across the isolation barrier
• Features fault-safe output configurations that default to a predetermined state upon power loss

Applications

• Inverter control systems
• Power supply monitoring and control
• Industrial fieldbus isolation interfaces
• PWM controller signal isolation

Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm package orientation and pinout alignment against the official datasheet specifications before integration. Ensure storage conditions account for moisture sensitivity levels to prevent soldering defects during assembly processes.

Selection Notes

Select this variant for designs requiring unidirectional isolation with high-speed data rates up to 150 Mbps. The wide-body SOIC package offers enhanced creepage distances suitable for high-voltage isolation requirements. Consider the specific fault-safe output polarity options when designing input circuits for critical safety applications.

Part Context

This component belongs to the ADuM320N series of dual-channel digital isolators. It represents a specialized version within the iCoupler family, distinguished by its AEC-Q100 automotive qualification and wide-body packaging. The part complements other isolators in the portfolio by offering a balance of speed, isolation strength, and thermal performance.

Replacement Considerations

Cross-reference with ADUM320N0BRIZ-RL for standard narrow-body alternatives or ADUM320N0WBRIZ for tube-packaged versions. Verify channel count and isolation voltage ratings match system requirements when substituting.
