ADUM141E0WBRQZ-RL7

Digital Isolators Overview

The ADUM141E0WBRQZ-RL7 is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four channels with three unidirectional forward paths and one reverse path. Key electrical parameters include a data rate of 150 Mb/s, propagation delay of 15 ns, and common mode transient immunity of 75 kV/µs. The device operates on a supply voltage range of 3 V to 5.5 V with a typical quiescent current of 11.4 mA per side. It offers an insulation voltage of 3750 Vrms and is qualified under AEC-Q100 for automotive applications. The operating temperature range spans from -40°C to +125°C, housed in a 16-pin WSOIC package.

Digital Isolators Feature Summary

• Integrates four isolated channels using proprietary iCoupler magnetic technology for high-speed signal transmission.
• Provides robust isolation with high common-mode transient immunity to protect against noise spikes.
• Meets AEC-Q100 automotive qualification standards for reliability in harsh environments.
• Supports wide supply voltage ranges and extended industrial temperature operations.

Digital Isolators Applications

• Automotive electronic control units requiring certified isolation
• Industrial communication interfaces such as CAN and LIN bus systems
• Medical equipment needing reinforced galvanic isolation
• Power conversion circuits with gate drive isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'WBRQZ' confirms the WSOIC-16 package and AEC-Q100 automotive qualification. Confirm the '-RL7' designation indicates reel packaging. Ensure the datasheet matches the required 3750 Vrms insulation rating, as non-Q variants may differ. Cross-reference the manufacturer part number directly with Analog Devices official documentation to avoid counterfeit components.

Digital Isolators Selection Notes

Select this component when automotive-grade certification (AEC-Q100) is mandatory. Choose over standard versions if the application requires the wider 3 V to 5.5 V supply range or the specific WSOIC footprint. Verify that the 150 Mb/s data rate meets system timing requirements. Consider the 3750 Vrms insulation level against safety regulations compared to lower-rated alternatives.

Digital Isolators Part Context

This part belongs to the ADUM141ES family of quad-channel digital isolators. It shares core functionality with the ADUM141 series but distinguishes itself through automotive qualification and specific packaging options. The 'E0' variant typically denotes the enhanced insulation rating compared to basic models.

Digital Isolators Replacement Considerations

Direct substitutes include other ADUM141 variants with matching AEC-Q100 status and WSOIC-16 packages. Check pin compatibility and insulation ratings carefully when considering non-automotive equivalents like the ADUM1411 or ADUM1412.
