ADUM1400BRW-RL

Overview

The ADUM1400BRW-RL is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides galvanic isolation with a voltage rating of 2500Vrms and a common mode transient immunity of 25kV/µs. The device supports data rates up to 90Mbps with bidirectional channel configuration. Operating parameters include a supply voltage range of 2.7V to 5.5V, propagation delay of 34ns, and an operating temperature range from -40°C to +125°C. It is housed in a 16-SOIC package.

Feature Summary

• Implements iCoupler magnetic coupling for high-speed digital signal isolation without external magnetics
• Provides bidirectional data transmission across four independent channels
• Ensures robust noise immunity through high common mode transient rejection capabilities

Applications

• Automotive electronic control units requiring AEC-Q100 qualified components
• Industrial communication interfaces such as RS-485 and CAN bus systems
• Medical equipment requiring strict galvanic isolation standards

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing. Confirm the component meets automotive qualification requirements if used in vehicle applications. Check current availability status as distribution may be limited. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component for designs requiring bidirectional isolation with high speed. Compare against unidirectional variants like ADUM1402 if directionality differs. Consider power consumption at maximum data rates versus lower speed alternatives. Validate thermal performance within the specified industrial temperature range.

Part Context

This part belongs to the ADuM1400 series of quad-channel digital isolators. It shares the core iCoupler architecture with other models in the family but differs in channel directionality and packaging options. The series is designed to replace traditional optocouplers in space-constrained applications.

Replacement Considerations

ADUM1400BRWZ is a tube-packaged equivalent. ADUM1400WTRWZ-RL offers wider temperature ratings. Verify pin compatibility before substitution.
