ADUM1402WTRWZ-RL

Overview

The ADUM1402WTRWZ-RL is a four-channel digital isolator manufactured by Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports bidirectional signal transmission across two channels for transmission and two for reception. The device provides an insulation voltage of 2500 Vrms and achieves data rates up to 90 Mb/s with a propagation delay of 34 ns. Designed for automotive applications, it holds AEC-Q100 qualification and functions reliably within an operating temperature range of -40°C to +125°C. Packaged in a 16-pin SOIC format on a reel.

Feature Summary

• Integrates high-speed CMOS logic with monolithic air-core transformer technology to provide robust galvanic isolation without optical components.
• Features bidirectional channel configuration allowing flexible signal routing between isolated circuit domains.
• Delivers superior common-mode transient immunity compared to traditional optocoupler alternatives.
• Eliminates the need for external discrete drivers or complex biasing circuits typically required by other isolation technologies.

Applications

• Automotive electronic control units requiring certified isolation interfaces
• Industrial communication bus systems such as CAN and LIN
• Medical equipment needing reinforced safety isolation barriers
• Power monitoring and metering devices

Procurement Notes

Verify that the specific suffix matches the required reel packaging configuration, as standard tube variants exist within the same family. Confirm AEC-Q100 automotive qualification status is explicitly documented for the intended application environment. Ensure the bidirectional channel mapping aligns with system design requirements before finalizing procurement orders.

Selection Notes

Select this component when bidirectional data flow is necessary across the isolation barrier. Compare performance against unidirectional variants if only single-direction signaling is required. Evaluate power consumption metrics relative to system battery constraints. Verify thermal performance specifications against maximum ambient operating temperatures in the target enclosure.

Part Context

This part belongs to the ADUM1402 series of digital isolators from Analog Devices. It represents a specialized variant optimized for reel-based surface mount assembly processes. The series leverages proprietary iCoupler technology to replace legacy optocouplers in modern interface designs.
