ADUM2210TRIZ

Overview

The ADUM2210TRIZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler technology for magnetic coupling isolation. It features a 5000 Vrms insulation voltage and supports data rates up to 10 Mb/s with a typical propagation delay of 50 ns. The device operates on a single power supply ranging from 3 V to 5.5 V, drawing approximately 1.6 mA per channel at 5 V. It is housed in a 16-lead SOIC package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• High isolation voltage capability of 5000 Vrms
• Enhanced system-level ESD performance compliant with IEC standards
• Low power operation suitable for battery-powered applications
• Bidirectional signal transmission with precise timing characteristics

Applications

• General purpose high voltage multi-channel isolation
• Medical equipment signal isolation
• Power supply control circuit isolation
• RS-232/RS-422/RS-485 transceiver isolation
• Hybrid electric vehicle battery monitoring

Procurement Notes

Verify the specific suffix 'TRIZ' corresponds to the tube packaging format rather than reel or cut tape variants when sourcing. Confirm that the component meets RoHS compliance requirements for your region. Ensure the supplier provides official documentation matching the Analog Devices part number to avoid counterfeit risks. Check for any regional distribution restrictions that may affect availability.

Selection Notes

Select this component when bidirectional isolation is required for two independent channels. Compare against the ADUM2211 if lower propagation delay is critical, as the ADUM2211 offers faster switching speeds. Consider the ADUM2210SRIZ if reel packaging is preferred over tubes. Evaluate power consumption needs against the 1.6 mA per channel specification at 5 V operation.

Part Context

This part belongs to the ADuM221x series of dual-channel digital isolators. It shares architectural similarities with the ADuM121x series but offers higher isolation voltage ratings. The iCoupler technology integrates monolithic air-core transformers on-chip, distinguishing it from optical couplers. This series is designed for robust performance in noisy industrial environments.

Replacement Considerations

The ADUM2211TRIZ serves as a functional substitute with identical pinout but faster propagation delay. The ADUM2210SRIZ is an alternative packaging variant (reel) of the same electrical device. Cross-reference datasheets to ensure compatibility with existing board layouts and thermal management strategies.
