ADUM120N1BRZ

Overview

The ADUM120N1BRZ is a dual-channel digital isolator utilizing magnetic coupling technology. It provides 3000 Vrms isolation voltage with a data rate of 150 Mbps. The device features unidirectional signal transmission across two channels. Key electrical parameters include a maximum propagation delay of 7.2 ns and an operating supply voltage range from 3 V to 5.5 V. It operates within a temperature range of -40°C to +125°C and is housed in an 8-SOIC package.

Feature Summary

• Employs iCoupler magnetic coupling technology for high-speed signal isolation
• Provides robust electromagnetic compatibility (EMC) performance
• Supports wide operating supply voltage ranges for flexible system integration

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Automotive electronic modules

Procurement Notes

Verify the specific suffix 'BRZ' against official Analog Devices documentation to confirm the tube packaging configuration, as other suffixes may indicate reel or tape-and-reel formats. Ensure the component meets AEC-Q100 automotive qualification requirements if intended for automotive applications. Cross-reference the datasheet revision date to ensure compliance with current RoHS directives and material declarations before finalizing procurement orders.

Selection Notes

Select this component when bidirectional isolation is not required, as it supports only unidirectional channels. Consider the 150 Mbps data rate limit for high-speed interface applications. Evaluate the 3000 Vrms isolation rating against system safety standards. The 8-SOIC package requires appropriate PCB footprint design. Verify that the 7.2 ns propagation delay meets timing constraints for the target communication protocol.
