ADUM142D1BRZ

Digital Isolators Overview

The ADUM142D1BRZ is a robust quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides four unidirectional channels with a data rate of 150 Mbps and a propagation delay of 13 ns. The device operates on a supply voltage range of 1.7 V to 5.5 V and offers an isolation voltage of 3000 Vrms. It features a common-mode transient immunity of 75 kV/µs and supports SPI protocols. Packaged in a 16-SOIC format, it functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Utilizes iCoupler magnetic coupling technology for high-speed signal transmission without external magnetics
• Provides robust isolation with 3000 Vrms insulation voltage and 75 kV/µs common-mode transient immunity
• Supports unidirectional data flow across four independent channels at speeds up to 150 Mbps

Digital Isolators Applications

• Automotive electronic systems requiring galvanic isolation
• Industrial communication interfaces such as SPI buses
• General-purpose digital isolation in noisy environments

Digital Isolators Procurement Notes

Verify the specific suffix 'BRZ' confirms the tube packaging variant rather than reel options. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check current availability as distribution may vary by region. Ensure the 16-SOIC footprint matches your PCB design constraints before ordering.

Digital Isolators Selection Notes

Select this component when unidirectional isolation is required for multiple signal lines simultaneously. The 150 Mbps speed suits most industrial and automotive digital protocols. Consider the 16-SOIC package width for board space limitations. Compare against the ADUM142D0BRZ if bidirectional or different channel configurations are needed instead.

Digital Isolators Part Context

This part belongs to the ADuM142D series of quad-channel digital isolators. It shares core specifications with other variants like the ADUM142D1BRZ-RL7 but differs in packaging type. The series is designed for applications demanding high reliability and noise immunity in compact form factors.

Digital Isolators Replacement Considerations

The ADUM142D1BRZ-RL7 serves as a parameter-equivalent alternative with identical electrical characteristics but utilizes tape-and-reel packaging instead of tubes.
