ADUM2211WSRWZ

Overview

The ADUM2211WSRWZ is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mbps. The device provides an isolation voltage of 5000 Vrms with a common-mode transient immunity of 25 kV/µs. Key electrical parameters include a propagation delay of 150 ns, typical rise/fall times of 10 ns, and power consumption of 1.1 mA on the primary side and 1.3 mA on the secondary side. It functions reliably across an industrial temperature range from -40°C to +125°C.

Feature Summary

• Dual independent isolation channels for signal transmission
• High common-mode transient immunity capability
• Integrated magnetic coupling technology eliminating external transformers

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment safety circuits
• Power metering and energy monitoring interfaces

Procurement Notes

Verify the specific suffix 'WSRWZ' against official Analog Devices documentation to confirm the wide SOIC-16 package and reel packaging configuration. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles specified in the datasheet. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when dual-channel isolation with high CMTI is required. Compare power consumption metrics against capacitive isolators if low standby current is critical. Verify that the 5000 Vrms insulation rating meets the safety standards of the target application environment. Confirm channel count requirements to ensure no unused channels impact system design.

Part Context

This device belongs to the ADuM221x family of general-purpose digital isolators. It shares the iCoupler architecture with other series members but differs in channel count and specific electrical characteristics. The WSRWZ designation indicates a specific tape-and-reel packaging variant suitable for automated surface-mount assembly processes.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADuM221x family. Verify that substitute parts maintain equivalent isolation voltage ratings and thermal performance. Ensure any replacement matches the specific SOIC-16 footprint and lead finish specifications.
