ADUM2211TRIZ-RL

Overview

The ADUM2211TRIZ-RL is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides galvanic isolation with an insulation voltage of 5000 Vrms and supports data rates up to 10 Mb/s. The device operates within a supply voltage range of 3 V to 5.5 V and features a common mode transient immunity of 25 kV/µs. Packaged in a 16-pin SOIC, it ensures signal integrity across isolated boundaries with propagation delays of approximately 50 ns.

Feature Summary

• Dual-channel unidirectional digital isolation for independent signal paths
• High common mode transient immunity to maintain stability in noisy environments
• Magnetic coupling technology eliminates the need for external transformer drivers

Applications

• Industrial communication bus isolation
• Medical equipment signal isolation
• Power metering systems

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the 16-SOIC package dimensions match your PCB footprint requirements. Check moisture sensitivity level ratings for proper storage and handling procedures during assembly.

Selection Notes

Select this component for applications requiring bidirectional data transmission support despite its unidirectional channel configuration per pinout. Compare propagation delay specifications against system timing budgets. Evaluate power consumption at 3 V versus 5.5 V operation to optimize thermal performance. Ensure the 5000 Vrms isolation rating meets safety standards for the target application environment.

Part Context

This part belongs to the ADUM2211 series of iCoupler digital isolators. It shares the same core architecture as the ADUM2211TRIZ but differs in packaging format. The series is designed for general-purpose isolation needs where high reliability and low power consumption are critical. It complements other single-channel variants in the family for scalable design solutions.

Replacement Considerations

The ADUM2211TRIZ is a compatible tube-packaged alternative offering identical electrical characteristics. Verify pin compatibility and package dimensions before substitution. Ensure the replacement part meets the same insulation voltage and data rate requirements.
