ADUM3211TRZ-EP

Overview

The ADUM3211TRZ-EP is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features two unidirectional channels with a data rate of 10 Mb/s and an insulation voltage of 2500 Vrms. The device operates on a supply voltage between 3 V and 5.5 V, drawing 6.4 mA of working power current. It exhibits a propagation delay of 50 ns and supports an operating temperature range from -40°C to +125°C. Housed in an SOIC-8 package, it provides enhanced system-level ESD reliability compared to traditional optocouplers.

Feature Summary

• Integrates high-speed CMOS logic with single-chip transformer technology for robust signal isolation.
• Provides bidirectional data transmission capability through dedicated input and output channels.
• Offers superior performance characteristics over conventional optocoupler alternatives.

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• General-purpose isolated communication interfaces

Procurement Notes

Verify the specific suffix EP indicates military or extended grade specifications as defined by Analog Devices documentation. Confirm that the SOIC-8 package matches your PCB footprint requirements. Ensure compatibility with the specified 3V to 5.5V supply range. Check for any moisture sensitivity level restrictions during storage and handling. Validate that the 2500 Vrms isolation rating meets your safety standards.

Selection Notes

Select this component when high common-mode transient immunity and low propagation delay are critical. Consider the 10 Mb/s data rate for bandwidth requirements. Evaluate the 6.4 mA power consumption against system efficiency goals. Compare the 50 ns delay against timing constraints in your application. Assess the thermal performance within the -40°C to +125°C operational window.
