ADUM3401WBRWZ-RL

Overview

The ADUM3401WBRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports bidirectional data transmission at speeds up to 90 Mb/s. The device provides an isolation voltage of 2500 Vrms with a propagation delay of 32 ns. It is housed in a 16-pin SOIC package and is qualified under the AEC-Q100 standard for automotive applications.

Feature Summary

• Integrates four independent channels for bidirectional signal isolation using proprietary magnetic coupling technology.
• Supports high-speed data transmission rates up to 90 Mb/s with low propagation delay characteristics.
• Features robust insulation capabilities rated at 2500 Vrms for reliable operation in noisy environments.
• Complies with AEC-Q100 qualification standards suitable for demanding automotive electronic systems.

Applications

• Automotive gate driver interfaces
• Industrial communication bus isolation
• Power converter control circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm specific packaging options such as reel or cut tape formats align with production requirements. Ensure compliance with RoHS directives and check for any recent product change notices affecting specifications or sourcing locations before finalizing procurement orders.

Selection Notes

Select this component when bidirectional isolation is required for multiple channels within a compact footprint. Consider the 2.7 V to 5.5 V operating range and 90 Mb/s speed limit against system needs. The AEC-Q100 qualification makes it appropriate for automotive designs requiring high reliability and thermal stability across the specified temperature range.

Part Context

This part belongs to the ADUM3401 series of quad digital isolators. It shares the same functional architecture as variants like the ADUM3401ARWZ-RL but differs in specific performance parameters such as data rate and power consumption. The WBRWZ suffix indicates a specific package and tape/reel configuration distinct from tube-packaged versions.

Replacement Considerations

Direct substitutes include other ADUM3401 variants such as ADUM3401ARWZ-RL or ADUM3401CRWZ depending on required data rates and packaging preferences. Verify pin compatibility and electrical specifications before swapping to ensure circuit integrity.
