ADUM3210BRZ

Overview

The ADUM3210BRZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler technology to integrate high-speed CMOS logic with monolithic transformer coupling. It provides electrical isolation between two circuits while transmitting digital signals. The device operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 10 Mb/s. Key electrical specifications include an insulation voltage of 2500 Vrms, a typical propagation delay of 50 ns, and rise/fall times of approximately 3 ns. It functions in unidirectional mode and is rated for operation between -40°C and +105°C.

Feature Summary

• Integrates high-speed CMOS technology with single-chip transformer isolation for robust signal transmission.
• Provides enhanced system-level electrostatic discharge (ESD) reliability compared to traditional optocouplers.
• Eliminates common optocoupler limitations such as poor temperature stability and limited lifetime.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power metering applications with high-voltage isolation requirements

Procurement Notes

Verify the specific package variant and tape/reel configuration against project requirements. Confirm that the SOIC-8 footprint matches the PCB design. Ensure compliance with RoHS directives if applicable. Check for any revision differences in the datasheet that may affect pinout or electrical characteristics. Validate supplier authenticity through authorized channels.

Selection Notes

Select this component when dual-channel isolation is required at speeds up to 10 Mb/s. Consider the 2500 Vrms insulation rating for safety-critical interfaces. Evaluate the 3 V to 5.5 V supply range compatibility with the target logic levels. Assess the thermal performance within the -40°C to +105°C operating window for environmental suitability.
