ADUM4402ARIZ

Overview

The ADUM4402ARIZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler technology for magnetic coupling isolation. It features four independent channels with unidirectional signal transmission and supports data rates up to 90 Mb/s. The device operates on a supply voltage range of 2.7 V to 5.5 V, drawing an operating current of 830 uA. It provides 5000 Vrms isolation voltage and is housed in a 16-pin SOIC package. Key timing parameters include a propagation delay of 32 ns and rise/fall times of 3 ns typical.

Feature Summary

• Implements iCoupler technology combining high-speed CMOS and monolithic air core transformer capabilities for robust isolation.
• Provides bidirectional communication support with integrated level translation between 3.3 V and 5 V domains.
• Ensures precise timing characteristics suitable for high-speed digital interfaces.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage isolation safety
• Power metering applications with isolated communication links

Procurement Notes

Verify the specific suffix (e.g., -RL) against your reel or cut-tape requirements, as packaging formats vary. Confirm RoHS compliance status through official documentation before integration. Ensure the 16-SOIC footprint matches your PCB layout constraints. Check for restricted availability notices from distributors, as stock levels may fluctuate. Validate that the 5kV isolation rating meets your system's safety standards.

Selection Notes

Select this component when four isolated channels are required within a single package to save board space. It is suitable for designs needing 5000 Vrms isolation with data rates up to 90 Mbps. Consider the 32 ns propagation delay for timing-sensitive applications. The wide operating temperature range supports harsh industrial environments. Ensure the 2.7 V to 5.5 V supply range aligns with your system power rails.
