ADUM1402WTRWZ55

Overview

The ADUM1402WTRWZ55 is a quad-channel digital isolator from Analog Devices, utilizing iCoupler technology for magnetic signal transmission. It provides four independent isolation channels with two inputs and two outputs per side. The device supports data rates up to 10 Mbps and offers a voltage isolation rating of 2500 Vrms. It operates within a supply voltage range of 3V to 5.5V and functions across an extended temperature range of -40°C to +125°C. Packaged in a 16-SOIC format, it is designed for high-reliability automotive applications.

Feature Summary

• Implements iCoupler magnetic coupling technology for galvanic isolation without external transformers
• Provides four independent bidirectional or unidirectional logic channels for general-purpose isolation
• Engineered for automotive environments with AEC-Q100 qualification standards

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial systems needing robust protection against high-voltage transients
• Medical equipment demanding strict electrical safety isolation standards

Procurement Notes

Verify the specific suffix '55' indicates automotive grade qualification distinct from standard commercial variants. Confirm package integrity upon receipt as moisture sensitivity requires proper handling. Ensure compatibility with system voltage levels before integration. Cross-reference official documentation for any recent lifecycle status changes.

Selection Notes

Select this component when automotive reliability and high common-mode transient immunity are required. Compare channel count and speed requirements against other iCoupler series members. Evaluate thermal performance within the specified operating temperature range. Consider pinout compatibility if replacing existing designs in SOIC-16 packages.

Part Context

This part belongs to the ADuM140x family of quad-channel digital isolators. It shares architectural similarities with the ADUM1400 and ADUM1401 but differs in specific qualification and operational parameters. The family utilizes silicon dioxide insulation layers for reliable long-term performance in harsh environments.

Replacement Considerations

Official substitutes include the ADUM1402WTRWZ. Verify functional equivalence regarding data rate and isolation voltage before substitution. Check for package compatibility and pin configuration alignment.
