ADUM1400WTRWZ-RL

Overview

The ADUM1400WTRWZ-RL is a four-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates on a supply voltage range of 2.7V to 5.5V with a typical quiescent current of 70mA per channel. The device provides bidirectional data transmission at speeds up to 90Mb/s, featuring a propagation delay of 34ns and rise/fall times of 2.5ns. It offers an isolation voltage of 2500Vrms and meets AEC-Q100 automotive qualification standards. Packaged in SOIC-16 tape and reel format, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates high-speed CMOS logic with monolithic air-core transformer technology for robust signal isolation.
• Provides bidirectional communication capability across all four isolated channels.
• Eliminates design constraints associated with optical couplers by removing the need for LED drivers or photodiodes.
• Delivers stable performance characteristics independent of temperature variations and aging effects.

Applications

• Automotive electronic control units requiring certified isolation interfaces
• Industrial automation systems with high noise immunity requirements
• Medical equipment needing reliable galvanic separation
• Power electronics monitoring circuits

Procurement Notes

Verify the specific suffix 'RL' indicates the reel packaging configuration distinct from tube variants. Confirm AEC-Q100 compliance status for automotive deployment. Ensure the bidirectional channel configuration matches system topology needs. Validate operating temperature ranges against environmental specifications.

Selection Notes

Select this component when bidirectional data transfer is required across four isolated channels. Consider the 90Mb/s data rate limit for high-speed applications. Evaluate the 70mA power consumption against thermal management capabilities. Compare against unidirectional alternatives if only single-direction flow is necessary.

Part Context

This part belongs to the ADUM1400 series of iCoupler digital isolators. It shares the core magnetic coupling architecture with other members but differs in channel directionality and packaging. The 'W' denotes wide temperature operation, while 'TRWZ' specifies the SOIC-16 package and RoHS compliance.

Replacement Considerations

ADUM1400WTRWZ serves as the tube-packaged equivalent. ADUM1401ARWZ-RL offers similar isolation but with unidirectional channels. Verify pinout compatibility and electrical parameters before substitution.
