ADUM3210CRZ

Overview

The ADUM3210CRZ is a dual-channel digital isolator from Analog Devices Inc., utilizing iCoupler technology. It features magnetic coupling for signal transmission with a data rate of 25 Mb/s and an insulation voltage of 2500 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, drawing a typical operating current of 7.6 mA. It exhibits a propagation delay of 50 ns and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in an 8-SOIC format, it supports bidirectional data flow.

Feature Summary

• Integrates high-speed CMOS logic with single-chip transformer technology for robust isolation
• Provides enhanced system-level ESD reliability compared to traditional optocouplers
• Supports bidirectional data transmission through magnetic coupling mechanisms

Applications

• General-purpose digital isolation in industrial systems
• Isolating communication buses such as SPI and I2C
• Protecting sensitive electronics in noisy environments

Procurement Notes

Verify the specific suffix and package type against the original design requirements. Confirm that the component meets all necessary environmental and electrical specifications for the intended application. Check for any obsolescence notices or alternative part recommendations from the manufacturer before finalizing procurement decisions.

Selection Notes

Select this component when bidirectional isolation is required at speeds up to 25 Mb/s. Ensure the operating voltage aligns with the 2.7 V to 5.5 V range. Consider the thermal performance and package constraints if deploying in high-temperature environments up to 125°C. Validate compatibility with existing circuit designs regarding pinout and signal integrity.

Part Context

This part belongs to the ADUM3210 series of dual-channel digital isolators. It shares architectural similarities with other iCoupler devices but is distinct in its specific speed and voltage ratings. The series is designed to replace optocouplers in applications demanding higher speed and lower power consumption while maintaining galvanic isolation.

Replacement Considerations

The ADUM3210CRZ is listed as obsolete. Parametric equivalents such as the ADUM1200BRZ may be available as substitutes. Verify functional compatibility and pinout alignment before transitioning to alternative parts.
