ADUM2211TRIZ

Digital Isolators Overview

The ADUM2211TRIZ is a dual-channel digital isolator from Analog Devices, 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 10 Mb/s. The device provides an insulation voltage of 5000 Vrms with a common mode transient immunity of 25 kV/µs. Key electrical parameters include a propagation delay of 50 ns and typical rise/fall times of 10 ns. It functions in unidirectional mode across an operating temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates two independent digital isolation channels using proprietary iCoupler magnetic technology for signal transmission.
• Provides high common-mode transient immunity to reject noise spikes in electrically noisy environments.
• Operates with low power consumption suitable for battery-powered or energy-efficient applications.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors
• Medical equipment interfaces needing reinforced safety isolation
• Power metering circuits for accurate signal measurement across potential differences

Digital Isolators Procurement Notes

Verify the specific suffix TRIZ confirms the SOIC-16 tube packaging format when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 3 V to 5.5 V supply voltage range. Check current availability status as distribution may vary by region.

Digital Isolators Selection Notes

Select this component for designs requiring dual-channel isolation with moderate data speeds. Compare against the ADUM2210 variant if bidirectional communication is required instead of unidirectional. Consider the ADUM5211 series if integrated DC/DC conversion is necessary for isolated power domains. Validate thermal performance within the -40°C to +125°C operational envelope.

Digital Isolators Part Context

This part belongs to the ADuM221x family of general-purpose digital isolators. It shares the same core iCoupler architecture as other members but differs in channel count and directionality. The TRIZ suffix denotes the specific tape-and-reel or tube packaging configuration for surface-mount assembly.
