ADUM142E1WBRQZ-RL7

Digital Isolators Overview

The ADUM142E1WBRQZ-RL7 is a robust quad-channel digital isolator from the ADUM142E series, manufactured by Analog Devices Inc. It utilizes iCoupler magnetic coupling technology to provide electrical isolation between circuits. The device features four unidirectional channels configured as two forward and two reverse paths. Key electrical specifications include a data rate of 150 Mb/s, an insulation voltage of 3750 Vrms, and a propagation delay of 15 ns. It operates within a supply voltage range of 1.8 V to 5 V and supports a working temperature range from -40°C to +125°C. The component is housed in a QSOP-16 package and holds AEC-Q100 qualification for automotive applications.

Digital Isolators Feature Summary

• Employs iCoupler magnetic coupling technology for signal transmission across isolation barriers without optical components.
• Provides robust quad-channel isolation with independent forward and reverse channel configurations.
• Features high common-mode transient immunity to maintain signal integrity in noisy environments.
• Supports wide operating voltage ranges and extended industrial temperature grades.

Digital Isolators Applications

• Automotive electronic control units requiring certified isolation
• Industrial communication interfaces such as RS-485 and CAN bus systems
• Medical equipment needing galvanic isolation for safety compliance
• Power conversion systems utilizing isolated gate drive signals

Digital Isolators Procurement Notes

Verify the specific suffix WBRQZ-RL7 to confirm the QSOP-16 package and reel packaging format. Confirm AEC-Q100 automotive qualification status if required for your design. Check current availability as distribution may be limited. Ensure compatibility with your board layout regarding the 16-pin narrow body outline dimensions.

Digital Isolators Selection Notes

Select this part when a quad-channel isolator with automotive certification is needed. Compare against the BRZ variant if a wider SOIC-16 package is preferred instead of the narrower QSOP-16. Consider the 3750 Vrms rating against higher voltage requirements found in other ADUM series members. Verify that the 150 Mb/s data rate meets your system's timing constraints.

Digital Isolators Part Context

This component belongs to the ADUM142E family of iCoupler digital isolators. It shares architectural similarities with the ADUM141E and ADUM143E series but differs in channel count and configuration. The 'E' designation indicates enhanced performance characteristics compared to earlier generations. The RL7 suffix denotes tape and reel packaging suitable for automated surface-mount assembly processes.

Digital Isolators Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the ADUM142D0BRQZ-RL7. Verify pinout compatibility and insulation voltage ratings before substitution. Other variants in the ADUM142 family may require package adaptation or circuit redesign due to differing physical footprints.
