ADUM7240CRZ-RL7

Overview

The ADUM7240CRZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mb/s. The device provides 1000 Vrms isolation voltage and exhibits a common-mode transient immunity of 15 kV/µs. Key timing parameters include a maximum propagation delay of 50 ns and typical rise/fall times of 2.5 ns. It is housed in an 8-SOIC package and functions as a unidirectional isolator with two channels.

Feature Summary

• Employs iCoupler magnetic coupling technology for galvanic isolation without external transformers.
• Provides high common-mode transient immunity to protect against noise spikes.
• Supports bidirectional signal transmission across the isolation barrier.

Applications

• Industrial communication bus isolation
• Medical equipment signal isolation
• Power metering and energy monitoring systems

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the reel packaging requirement. Check current availability status as supply may be limited. Ensure compliance with RoHS directives and moisture sensitivity levels before integration into production workflows.

Selection Notes

Select this component when dual-channel isolation is required with moderate data rates. Consider the 8-SOIC footprint for space-constrained designs. Evaluate power consumption requirements against the specified operating current. Ensure the isolation voltage rating meets the system's safety standards.

Part Context

This part belongs to the ADUM7240 series of digital isolators. It shares architectural similarities with other iCoupler devices but offers specific channel counts and performance metrics tailored for general-purpose isolation applications. The RL7 suffix indicates tape and reel packaging for automated assembly.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Verify pin compatibility and electrical specifications if considering alternative manufacturers. Consult Analog Devices for recommended upgrades or cross-references.
