ADUM141D1BRZ

Digital Isolators Overview

The ADUM141D1BRZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It features four forward channels and one reverse channel, supporting data rates up to 150 Mb/s with a propagation delay of 15 ns. The device operates on a supply voltage range of 1.7 V to 5.5 V and provides an insulation voltage of 3750 Vrms. It includes SPI protocol support and exhibits a common-mode transient immunity of 75 kV/µs. The component is housed in a 16-pin SOIC package and functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four unidirectional forward channels and one reverse channel for versatile signal isolation.
• Employs iCoupler magnetic coupling technology to achieve high-speed data transmission without optical components.
• Supports standard communication protocols including SPI for robust interface isolation.

Digital Isolators Applications

• Automotive electronic control units requiring AEC-Q100 qualified isolation
• Industrial automation systems needing robust noise immunity
• Medical equipment demanding high insulation voltage safety

Digital Isolators Procurement Notes

Verify the specific suffix and package type against official Analog Devices documentation to ensure compatibility with design requirements. Confirm that the 3750 Vrms insulation rating meets system safety standards. Check for availability constraints as distribution status may vary by region. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Digital Isolators Selection Notes

Select this component when a combination of four forward and one reverse isolated channel is required. The 150 Mb/s data rate suits moderate-speed digital interfaces. Consider the 1.7 V minimum supply voltage for low-power applications. Verify that the 16-pin SOIC package fits the PCB layout constraints and thermal management needs.
