ADUM320N0WBRIZ

Overview

The ADUM320N0WBRIZ is a dual-channel digital isolator from the ADUM320N series, manufactured by Analog Devices Inc. It utilizes iCoupler technology to provide robust signal isolation in an 8-pin SOIC package. The device supports unidirectional data transmission with a maximum data rate of 150 Mb/s and a typical propagation delay of 6.2 ns (maximum 10 ns). It operates on supply voltages ranging from 2.25 V to 5.5 V, ensuring compatibility with lower voltage systems. Key electrical specifications include a common-mode transient immunity of 100 kV/µs and a pulse width distortion of less than 3 ns. The component is qualified under AEC-Q100 standards for automotive applications and functions within a temperature range of -40°C to +125°C.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix 'IZ' indicates the wide-body SOIC_IC package variant when sourcing replacements. Confirm AEC-Q100 qualification status is required for the target automotive application. Ensure the ordering part number matches the exact channel configuration and polarity requirements. Cross-reference datasheet revision dates to ensure compatibility with existing design constraints.

Selection Notes

Select this component for designs requiring bidirectional or unidirectional isolation with high speed and low latency. The wide operating voltage range allows flexibility in system architecture. Consider the thermal performance and package size constraints during PCB layout. Verify that the isolation voltage ratings meet the safety standards of the end application environment.

Part Context
