ADUM2211TRWZ

Digital Isolators Overview

The ADUM2211TRWZ is a dual-channel digital isolator utilizing Analog Devices iCoupler technology. It provides magnetic coupling isolation with a rated insulation voltage of 5000 Vrms and a common-mode transient immunity of 25 kV/µs. The device supports data rates up to 10 Mb/s with a propagation delay of 50 ns. It operates on a single power supply ranging from 3 V to 5.5 V, consuming low quiescent current. Packaged in a 16-pin SOIC_W (Wide) surface-mount format, it functions within an industrial temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• High-voltage isolation capability of 5000 Vrms for robust signal transmission across potential barriers
• Enhanced system-level ESD protection performance compliant with IEC 61000-4-x standards
• Low-power operation suitable for energy-efficient designs using CMOS and air core transformer technology

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-reliability signal separation
• Power metering applications involving isolated communication interfaces

Digital Isolators Procurement Notes

Verify the specific suffix TRWZ corresponds to the tube packaging configuration when ordering. Confirm that the 16-pin SOIC_W footprint matches your PCB layout requirements. Ensure the 5000 Vrms insulation rating meets the safety regulations applicable to your target market. Cross-reference the operating temperature range with your environmental specifications before finalizing component selection.

Digital Isolators Selection Notes

Select this component when dual-channel isolation is required at speeds up to 10 Mb/s. It is appropriate for designs demanding high common-mode transient immunity and strong ESD resilience. Consider the 16-pin package size relative to available board space. Verify that the 3 V to 5.5 V supply range aligns with the system's power architecture.

Digital Isolators Part Context

This part belongs to the ADuM221x series of digital isolators based on iCoupler technology. It serves as a high-speed alternative to traditional optocouplers, offering improved reliability and lower power consumption. The series integrates CMOS logic with monolithic air core transformers to provide bidirectional or unidirectional signal isolation without optical components.

Digital Isolators Replacement Considerations

Check the ADUM2210 datasheet for pin-compatible alternatives within the same family. Verify if the ADUM2211ARWZ variant offers different thermal or electrical characteristics. Ensure any substitute maintains the 5000 Vrms insulation rating and 10 Mb/s data rate.
