ADUM1402WTRWZ53-RL

Overview

The ADUM1402WTRWZ53-RL is a four-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides bidirectional signal isolation with a rated isolation voltage of 2500 Vrms. The device operates within a supply voltage range of 2.7V to 5.5V and supports data rates up to 90 Mb/s. Key electrical characteristics include a typical propagation delay of 34 ns and rise/fall times of 2.5 ns. It is housed in a 16-pin SOIC package and is qualified under the AEC-Q100 standard for automotive applications.

Feature Summary

• Four independent channels providing general-purpose digital isolation
• iCoupler technology using on-chip transformer isolation
• AEC-Q100 qualified for automotive reliability standards

Applications

• Automotive electronic control units
• Industrial fieldbus isolation
• General-purpose multi-channel isolation

Procurement Notes

Verify the specific suffix '53' against official manufacturer documentation to confirm pinout or functional variations compared to standard variants. Confirm current production status as some listings indicate obsolescence. Ensure compatibility with required isolation voltage ratings and operating temperature ranges for the target application environment.

Selection Notes

Select this component when high-density four-channel isolation is required in a compact SOIC-16 package. Consider its AEC-Q100 qualification if deploying in automotive systems. Evaluate the 90 Mb/s data rate capability against system timing requirements. Compare power consumption and propagation delay specifications against alternative isolators to ensure fit for the specific interface protocol.

Part Context

This part belongs to the ADUM1402 series of iCoupler digital isolators. It shares the same core architecture and channel count as other variants in the family but may differ in packaging, tape/reel configuration, or specific automotive qualification details indicated by the suffix.

Replacement Considerations

Check for direct substitutes such as ADUM1402WTRWZ or ADUM1402ARWZ-RL. Verify that any replacement maintains the 16-SOIC footprint and AEC-Q100 qualification if automotive use is intended.
