ADUM320N0WBRZ

Overview

The ADUM320N0WBRZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler technology. It features two unidirectional channels 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 between 2.25 V and 5.5 V, drawing 3.1 mA at 5 V. It offers high common-mode transient immunity of 180 kV/µs and meets AEC-Q100 automotive standards. Packaged in an SOIC-8, it provides isolation ratings up to 5700 VRMS.

Feature Summary

• Integrates CMOS and monolithic air-core transformer technology for robust signal isolation
• Provides high common-mode transient immunity to suppress radiated and conducted noise
• Supports voltage translation across the isolation barrier between different logic levels
• Includes fault-safe output options that default to a predetermined state during power loss

Applications

• Inverter control systems
• Industrial fieldbus isolation
• PWM controller signal isolation
• General-purpose multi-channel isolation

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging type and orientation. The 'W' indicates wide body SOIC, while 'N' denotes narrow body. Ensure the '0' suffix matches the required fault-safe output polarity. Confirm AEC-Q100 qualification status if automotive compliance is mandatory for the target application environment.

Selection Notes

Select this component when bidirectional communication is not required, as it supports only unidirectional data flow. Choose based on the necessary isolation voltage rating and package width constraints. Consider the fault-safe output requirement to determine between N0 and N1 variants. Verify thermal dissipation capabilities within the SOIC-8 package for the intended operating temperature range.

Part Context

This part belongs to the ADUM320N series of dual-channel digital isolators. It shares core specifications with other variants in the family, differing primarily in package dimensions and manufacturing revisions. The series is designed for applications requiring reliable galvanic isolation with low power consumption and high speed.

Replacement Considerations

ADUM320N0WBRIZ is a compatible alternative within the same series offering identical electrical performance in a narrow-body SOIC-8 package.
