ADUM4402ARWZ-RL

Overview

The ADUM4402ARWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. 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 an insulation voltage of 5000 Vrms and features enhanced ESD protection. Key electrical parameters include a typical propagation delay of 32 ns and rise/fall times of 3 ns. It functions reliably across an operating temperature range of -40°C to +105°C and is housed in a SOIC-16 package.

Feature Summary

• Quad-channel configuration with unidirectional signal paths
• High-speed data transmission capability up to 90 Mb/s
• Robust 5 kV RMS insulation voltage rating
• Integrated enhanced electrostatic discharge (ESD) protection

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage safety barriers
• Power electronics control circuits
• Instrumentation interfaces

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Check current availability as distribution may vary by region. Ensure the SOIC-16 package matches your PCB footprint requirements. Validate that the 5000 Vrms isolation rating meets your system's safety standards.

Selection Notes

Select this component when high data rates near 90 Mb/s are required alongside strong isolation capabilities. The quad-channel design reduces board space compared to single-channel alternatives. Consider the 2.7 V to 5.5 V supply range compatibility with your logic levels. The enhanced ESD feature adds robustness against transient events in noisy environments.

Part Context

This part belongs to the ADuM4402 series of digital isolators. It shares the SOIC-16 package form factor with other devices in the ADUM family but offers distinct performance characteristics. The magnetic coupling method differentiates it from capacitive or optical isolation technologies. It serves as a specialized interface solution for demanding industrial applications.
