ADUM1402WTRWZ55-RL

Overview

The ADUM1402WTRWZ55-RL is a quad-channel digital isolator utilizing iCoupler technology, housed in a 16-SOIC package. It provides bidirectional data transmission with a data rate of 90 Mb/s and isolation voltage of 2500 Vrms. Operating on a supply voltage range of 2.7V to 5.5V, it features a typical propagation delay of 34 ns and operates within a temperature range of -40°C to +125°C. The device includes AEC-Q100 qualification for automotive applications.

Feature Summary

• Quad-channel architecture enabling four independent isolated signal paths
• High common-mode transient immunity (CMTI) for noise rejection
• iCoupler magnetic coupling technology eliminating transformer limitations
• AEC-Q100 qualified for automotive reliability standards

Applications

• Automotive gate driver interfaces
• Industrial communication bus isolation
• Medical equipment signal isolation
• Power converter control loops

Procurement Notes

Verify the specific suffix '55-RL' against current manufacturer documentation, as availability may vary. Confirm RoHS compliance status and check for any obsolescence notices or lifecycle changes directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when high-speed bidirectional isolation is required in space-constrained designs. Ensure the 90 Mb/s data rate meets system timing requirements. Verify that the 2500 Vrms isolation rating satisfies safety regulatory standards for the target application environment.

Part Context

This part belongs to the ADUM1402 series of general-purpose digital isolators. It shares architectural similarities with the ADUM1400 and ADUM1401 but offers higher data rates suitable for demanding industrial and automotive protocols. The reel packaging indicates suitability for automated surface-mount assembly processes.

Replacement Considerations

Publicly confirmed substitutes include the ADUM1402WTRWZ. Verify pinout compatibility and electrical parameter equivalence before substitution.
