ADUM2402ARWZ-RL

Overview

The ADUM2402ARWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7V to 5.5V and supports data rates up to 1 Mb/s. The device features unidirectional signal transmission with four channels configured as two inputs and two outputs. Key electrical specifications include a maximum propagation delay of 100 ns, typical rise and fall times of 2.5 ns, and a common-mode transient immunity of 25 kV/µs. It provides an isolation voltage rating of 5000 Vrms and functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates high-speed CMOS logic with monolithic air core transformer technology for robust magnetic signal coupling.
• Provides galvanic isolation between circuits to prevent ground loops and protect against overvoltage conditions.
• Offers precise timing characteristics with low pulse width distortion and channel-to-channel matching.

Applications

• Industrial automation systems requiring reliable signal isolation
• Motor drive control circuits
• Power supply monitoring interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix indicates reel packaging. Check current availability status as supply may be limited. Ensure compliance with RoHS directives and relevant safety certifications before integration into final products.

Selection Notes

Select this component when four isolated channels are required for unidirectional data transfer at speeds up to 1 Mbps. Consider the 16-SOIC package dimensions for PCB layout constraints. Evaluate the 5000 Vrms isolation rating against system safety requirements. Compare power consumption metrics if battery operation is critical.
