ADUM2402ARWZ

Overview

The ADUM2402ARWZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 5000Vrms isolation with a data rate of 1Mbps and 25kV/µs common-mode transient immunity. The device operates on a 2.7V to 5.5V supply, features unidirectional channels in a 16-SOIC package, and supports temperatures from -40°C to 105°C.

Feature Summary

• Integrates four independent isolation channels using monolithic air core transformer technology for high-speed signal transmission.
• Provides robust noise immunity with high common-mode transient rejection capabilities suitable for noisy industrial environments.
• Supports bidirectional communication and level translation between 3V and 5V logic domains without external components.

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment signal interfaces
• Power metering and energy monitoring circuits

Procurement Notes

Verify the specific suffix (RWZ) against the manufacturer's current datasheet to confirm package dimensions and tape/reel specifications. Ensure compliance with RoHS3 standards as indicated in official documentation. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when four isolated channels are required within a single package footprint. It is suitable for applications needing moderate data rates up to 1Mbps with high voltage isolation requirements. Consider thermal management for operation near the upper temperature limit.

Part Context

This part belongs to the ADuM240x family of quad-channel digital isolators. These devices combine high-speed CMOS technology with monolithic air core transformer technology to provide superior performance compared to traditional optocouplers in terms of speed, power consumption, and reliability.

Replacement Considerations

Check for direct substitutes within the ADuM2400 or ADuM2401 series if channel count or specific electrical parameters differ slightly. Verify pin compatibility and isolation voltage ratings before substitution.
