ADUM141E1WBRWZ-RL

Digital Isolators Overview

The ADUM141E1WBRWZ-RL is a robust quad digital isolator from the iCoupler series, manufactured by Analog Devices Inc. It features four independent channels with a 3:1 input-to-output configuration (three unidirectional forward channels and one reverse channel). The device utilizes magnetic coupling technology to provide electrical isolation with a rated insulation voltage of 3750 Vrms. It supports data rates up to 150 Mb/s and operates within a supply voltage range of 1.7 V to 5.5 V. Key performance metrics include a typical propagation delay of 15 ns, rise and fall times of 2.5 ns, and a minimum common-mode transient immunity of 75 kV/µs. It is AEC-Q100 qualified for automotive applications and functions reliably across an operating temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides galvanic isolation via on-chip transformer-based magnetic coupling technology.
• Offers high common-mode transient immunity to reject noise in noisy environments.
• Supports bidirectional communication through a combination of forward and reverse channels.
• Meets automotive reliability standards with AEC-Q100 qualification.

Digital Isolators Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems needing robust signal isolation
• Medical equipment requiring safety-certified isolation barriers

Digital Isolators Procurement Notes

Verify the specific suffix WBRWZ to confirm the SOIC-16 wide-body package and reel packaging format. Ensure the E1 grade matches the required insulation voltage and automotive qualification level. Confirm availability status as distribution may vary by region. Check RoHS compliance details if restricted substances are a constraint for your assembly process.

Digital Isolators Selection Notes

Select this component when high isolation voltage and automotive qualification are required. The 3:1 channel configuration suits applications needing three outputs from one input or mixed directional flows. Compare against standard industrial grades if automotive certification is unnecessary. Consider the SOIC-16 footprint constraints during PCB layout planning.

Digital Isolators Part Context

This part belongs to the ADUM141ES series of digital isolators. It is designed to replace optocouplers in many applications, offering smaller size, lower power consumption, and better performance consistency. The iCoupler technology integrates isolation barriers directly into the silicon die.

Digital Isolators Replacement Considerations

Direct pin-compatible replacements within the same family include ADUM141E0 variants, though insulation ratings may differ. Cross-referencing with other iCoupler products requires verifying channel count and isolation voltage specifications.
