ADUM2402ARIZ-RL

Overview

The ADUM2402ARIZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports bidirectional data transmission at rates up to 90 Mb/s. The device features a propagation delay of 100 ns, with rise and fall times of 3 ns each. It provides an isolation voltage of 5000 Vrms and functions reliably across an operating temperature range of -40°C to +105°C. Packaged in a 16-pin SOIC format on a reel, it draws 44 mA during operation.

Feature Summary

• Implements iCoupler magnetic coupling for high-speed digital isolation without external transformers
• Supports bidirectional communication channels with integrated level translation capabilities
• Delivers precise timing characteristics including low pulse width distortion and channel-to-channel matching

Applications

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

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and tape/reel specifications. Confirm availability status as distribution listings may indicate limited stock or discontinuation. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles before procurement.

Selection Notes

Select this component when bidirectional data flow is required alongside high data rates up to 90 Mb/s. Compare against unidirectional variants like the ADUM2402ARIZ if lower power consumption at reduced speeds is sufficient. Validate that the 16-pin SOIC footprint fits the design constraints and that the 44 mA current draw aligns with thermal management capabilities.

Part Context

This part belongs to the ADUM2402 series of quad-channel digital isolators. It shares the core iCoupler architecture with other family members but differs in directionality and speed specifications. The 'ARIZ' designation indicates the industrial temperature grade and SOIC-16 package, while '-RL' specifies the reel packaging format for automated assembly.

Replacement Considerations

The ADUM2402CRIZ-RL serves as a functional substitute within the same series, offering similar bidirectional capabilities and magnetic coupling technology. Verify pinout compatibility and ensure the replacement meets the specific insulation voltage and data rate requirements of the original design.
