ADUM2400CRIZ

Overview

The ADUM2400CRIZ 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 data rates up to 90 Mb/s. The device provides bidirectional communication with an isolation rating of 5000 Vrms. Key electrical parameters include a propagation delay of 32 ns, rise/fall times of 3 ns, and a common-mode transient immunity of 25 kV/µs. It functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates four independent channels for high-density signal isolation
• Employs on-chip transformer technology for robust magnetic coupling
• Supports bidirectional data transmission with CMOS logic levels

Applications

• Industrial automation control systems
• Medical equipment signal interfaces
• Power electronics gate drive circuits

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and reel specifications. Confirm RoHS compliance status through current manufacturer declarations. Check for obsolescence notices or lifecycle changes directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when four isolated channels are required in a single package. Ensure the design accommodates the 70 mA typical supply current. Verify that the SOIC-16 footprint matches the PCB layout constraints. Confirm that the 5000 Vrms isolation rating meets the safety requirements of the target application environment.

Part Context

This part belongs to the ADUM2400 series of quad-channel digital isolators. It shares architectural similarities with other iCoupler devices but offers higher channel density compared to dual-channel variants like the ADUM7240. The series is designed for applications requiring galvanic isolation between different ground domains.

Replacement Considerations

The ADUM2402CRIZ is a documented alternative within the same family. Verify pinout compatibility and functional equivalence before substitution.
