ADUM3210ARZ-RL7

Overview

The ADuM3210ARZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features two independent unidirectional channels with a data rate of 1 Mbps and a typical propagation delay of 50 ns. The device operates on a supply voltage range of 3 V to 5.5 V and provides an isolation voltage of 2500 Vrms. It offers a common mode transient immunity of 25 kV/µs and is housed in an 8-pin SOIC package.

Feature Summary

• Employs iCoupler magnetic coupling technology to eliminate LED and photodiode dependencies found in optocouplers.
• Provides enhanced system-level ESD reliability compared to traditional isolation alternatives.
• Supports voltage translation functionality across the isolation barrier for mixed-voltage systems.

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal transmission interfaces
• Power metering and energy monitoring circuits

Procurement Notes

Verify the specific suffix RL7 indicates tape-and-reel packaging when sourcing components. Confirm that the part number matches the exact manufacturer designation from Analog Devices Inc. documentation to ensure compatibility with design specifications. Cross-reference datasheet revisions to validate current electrical characteristics before integration into production.

Selection Notes

Select this component for applications requiring bidirectional voltage translation and robust ESD protection. The unidirectional channel configuration suits simple signal transmission needs. Ensure the operating temperature range of -40°C to +125°C aligns with environmental constraints. Verify power consumption requirements against the specified 2 mA and 3.5 mA operating currents.

Part Context

This device belongs to the ADuM3210 series of dual-channel digital isolators. It serves as a modern replacement for optocouplers by offering superior performance characteristics through silicon-based magnetic coupling. The series is designed to address design difficulties associated with lifetime effects and uncertain parameters in traditional optical isolation devices.

Replacement Considerations

The ADUM3210ARZ is the tube-packaged equivalent of the ADUM3210ARZ-RL7. Both share identical electrical specifications and pinouts. Substitution depends primarily on packaging preference for assembly processes rather than functional differences.
