ADUM2402CRWZ-RL

Overview

The ADUM2402CRWZ-RL is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides four independent isolation channels with a data rate of 90 Mb/s and a common-mode transient immunity (CMTI) of 25 kV/µs. The device operates on a single power supply ranging from 2.7 V to 5.5 V, drawing a typical operating current of 44 mA. Key timing parameters include a propagation delay of 27 ns and rise/fall times of 3 ns. It features an insulation voltage rating of 5000 Vrms and functions within an industrial temperature range of -40°C to +105°C.

Feature Summary

• Integrates four isolated digital channels using proprietary iCoupler magnetic coupling technology for robust signal transmission.
• Provides high common-mode transient immunity to ensure accurate data transfer in electrically noisy environments.
• Features Schmitt trigger inputs to enhance noise rejection and maintain signal integrity across the isolation barrier.

Applications

• Isolating CMOS digital I/O interfaces in industrial automation systems
• Protecting sensitive local ground circuits from noise and surges on data buses
• General-purpose digital isolation in measurement and control equipment

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and reel specifications. Confirm that the component meets required RoHS compliance standards for your target market. Ensure the procurement channel is authorized to guarantee authenticity and traceability of the magnetic coupling technology used in this series.

Selection Notes

Select this component when four independent bidirectional or unidirectional channels are required without integrated isolated power supplies. Compare the 90 Mb/s data rate against higher-speed alternatives if system throughput demands exceed this limit. Evaluate the 5000 Vrms insulation rating against safety standards applicable to the specific application environment.

Part Context

This part belongs to the ADUM2402 series of quad-channel digital isolators. It shares the same core architecture as the non-reel variant ADUM2402CRWZ but is supplied in tape-and-reel packaging for automated assembly. The series represents Analog Devices' implementation of iCoupler technology, distinguishing it from capacitive or optical isolation solutions.
