ADUM141E0BRZ

Digital Isolators Overview

The ADUM141E0BRZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four independent channels with three unidirectional forward paths and one reverse path. The device supports data rates up to 150 Mb/s and offers a common-mode transient immunity of 75 kV/µs. It operates on a supply voltage range of 1.7 V to 5.5 V with a typical quiescent current of 11.4 mA per side. The isolation rating is 3000 Vrms for the BRZ variant, with a propagation delay of 15 ns. It functions within an operating temperature range of -40°C to +125°C and is housed in a 16-lead SOIC package.

Digital Isolators Feature Summary

• Integrates four isolated channels using proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Provides robust electrical isolation with a 3000 Vrms insulation rating and high common-mode transient immunity.
• Supports flexible bidirectional communication through a configuration of three forward and one reverse channel.
• Operates reliably across a wide industrial temperature range with low power consumption characteristics.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors.
• Medical equipment interfaces needing certified isolation for patient safety compliance.
• Automotive electronics applications adhering to AEC-Q100 qualification standards.
• Power metering circuits isolating high-voltage measurement sections from low-voltage processing units.

Digital Isolators Procurement Notes

Verify the specific suffix designation to confirm the insulation voltage rating, as variants exist with different isolation levels. Confirm the package type matches the PCB footprint requirements, noting that tape-and-reel options may differ from tube packaging. Ensure the selected component meets the required automotive or industrial qualification standards if applicable to the end product design constraints.

Digital Isolators Selection Notes

Select this component when a quad-channel solution with mixed directional capabilities is required. Compare the 3000 Vrms rating against system isolation needs; higher ratings may require alternative models like the ADUM141E0WBRZ. Evaluate the 150 Mbps speed against signal requirements, as lower-speed applications might utilize cost-effective dual-channel alternatives. Consider the 1.7 V minimum supply voltage for compatibility with low-power logic families.

Digital Isolators Part Context

This part belongs to the ADuM141ES series of digital isolators. It represents a generation of devices leveraging silicon dioxide and copper coil technology for isolation. The series includes variants with different channel counts and isolation ratings, designed to replace traditional optocouplers in space-constrained designs.

Digital Isolators Replacement Considerations

The ADUM141E0WBRZ serves as a direct substitute offering enhanced 3750 Vrms isolation while maintaining identical pinouts and functionality. Other family members like the ADUM141E1 provide similar performance but may differ in channel directionality or specific certification status.
