ADUM2402CRIZ-RL

Overview

The ADUM2402CRIZ-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 speeds up to 90 Mb/s. The device provides 5000 Vrms isolation voltage and exhibits a common-mode transient immunity of 25 kV/µs. Key timing parameters include a propagation delay of 32 ns and rise/fall times of 3 ns. It functions reliably across an industrial temperature range of -40°C to +105°C and is housed in a 16-SOIC package.

Feature Summary

• Integrates four independent bidirectional channels for high-density signal isolation
• Employs on-chip transformer-based magnetic coupling for robust noise immunity
• Delivers high common-mode transient immunity to prevent false triggering
• Supports standard CMOS logic levels with low power consumption

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment needing safety-certified signal separation
• Power electronics interfaces for gate drive and feedback loops
• Inverters and motor drives with high-voltage isolation requirements

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm channel directionality and speed ratings, as variations exist within the family. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Ensure the reel packaging matches your automated pick-and-place equipment specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability and authenticity.

Selection Notes

Select this component when bidirectional communication is required across the isolation barrier. The 90 Mb/s data rate suits most standard industrial protocols but may be insufficient for ultra-high-speed applications. Consider the 16-SOIC footprint for PCB layout constraints. Evaluate the 5000 Vrms isolation rating against system safety standards. Compare power consumption figures if battery-operated designs are involved.

Part Context

This part belongs to the ADUM2402 series of quad-channel digital isolators. It shares the same physical package and basic isolation architecture with other variants like the unidirectional ADUM2402CRIZ. The primary distinction lies in the internal channel configuration and resulting data rate capabilities. The series represents Analog Devices' iCoupler technology implementation for general-purpose isolation needs.

Replacement Considerations

Direct substitutes include the ADUM2402ARIZ-RL, though it offers lower performance metrics such as reduced data rates and pulse width distortion limits. Verify pin compatibility and electrical characteristics before swapping. No other direct equivalents are confirmed in public documentation.
