ADUM1402BRWZ

Overview

The ADUM1402BRWZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 2500Vrms isolation with a common-mode transient immunity of 25kV/µs. The device supports data rates up to 10Mbps and operates on a single supply voltage ranging from 2.7V to 5.5V. It features unidirectional channel directionality in a 2/2 configuration within a 16-SOIC package. The component functions across an industrial temperature range of -40°C to 105°C.

Feature Summary

• Integrates four independent digital channels using proprietary iCoupler magnetic coupling for galvanic isolation.
• Provides high common-mode transient immunity to reject noise in electrically noisy environments.
• Supports bidirectional signal transmission with configurable channel directionality.
• Operates reliably across extended industrial temperature ranges without external components.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics monitoring circuits
• Automotive sensor interface modules

Procurement Notes

Verify the specific suffix Z indicates RoHS compliance when sourcing. Confirm package dimensions match the 16-SOIC specification. Check manufacturer documentation for current lifecycle status as availability may vary. Ensure voltage ratings align with system requirements before integration.

Selection Notes

Select this component when four isolated channels are required in a compact footprint. Consider the 2500Vrms isolation rating for safety-critical applications. Evaluate the 10Mbps data rate against system speed requirements. Verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to the ADuM1402 series of quad-channel digital isolators. It represents Analog Devices' implementation of iCoupler technology, replacing traditional transformer-based isolation solutions. The series offers integrated logic and magnetic coupling on a single silicon substrate.

Replacement Considerations

ADUM1402BRWZ-RL is a reel-packaged variant of the same functional device. Verify pinout compatibility and electrical specifications match exactly before substitution. Ensure packaging differences do not impact assembly processes.
