ADUM141E1WBRQZ-RL7

Digital Isolators Overview

The ADUM141E1WBRQZ-RL7 is a robust quad-channel digital isolator from the ADUM141ES series, manufactured by Analog Devices Inc. It utilizes iCoupler magnetic coupling technology to provide electrical isolation between circuits. The device features four channels with a 3:1 input-to-output configuration (three forward, one reverse) and supports unidirectional data transmission at speeds up to 150 Mb/s. It operates within a supply voltage range of 1.7 V to 5.5 V and offers an insulation voltage of 3750 Vrms. Key performance metrics include a propagation delay of 15 ns, a typical rise/fall time of 2.5 ns, and a minimum common-mode transient immunity of 75 kV/µs. It is housed in a 16-pin QSOP package and is qualified under AEC-Q100 standards for automotive applications.

Digital Isolators Feature Summary

• Integrates four independent digital isolation channels using proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Provides robust protection against common-mode transients with a specified immunity rating of 75 kV/µs.
• Supports wide operating supply voltages ranging from 1.7 V to 5.5 V, ensuring compatibility with various logic families.
• Meets AEC-Q100 qualification standards, ensuring reliability for demanding automotive electronic environments.

Digital Isolators Applications

• Automotive motor control systems requiring isolated gate drive signals

Digital Isolators Procurement Notes

Verify the specific suffix 'QZ' indicates the QSOP-16 package variant when sourcing. Confirm that the 'E1' designation aligns with the required 3750 Vrms insulation rating and AEC-Q100 automotive qualification. Ensure the ordering part number matches the exact channel configuration and polarity requirements for the target design.

Digital Isolators Selection Notes

Select this component when a quad-channel isolator with automotive qualification is required. It is suitable for designs needing 3750 Vrms isolation strength and high common-mode transient immunity. Consider the 15 ns propagation delay and 150 Mb/s data rate limits for timing-critical applications. Verify that the QSOP-16 footprint fits the PCB layout constraints compared to standard SOIC options.

Digital Isolators Part Context

This part belongs to the ADUM141ES family of robust quad-channel digital isolators. It shares functional similarities with other members like the ADUM141E0 series but differs in insulation voltage ratings and automotive qualification status. The 'QZ' suffix specifically denotes the QSOP-16 package, distinguishing it from standard SOIC or WSOIC variants within the same product line.
