ADUM5400ARWZ-RL

Overview

The ADUM5400ARWZ-RL is a quad-channel digital isolator from Analog Devices, featuring an integrated isolated dc-to-dc converter. It provides four independent data channels with unidirectional signal transmission at a maximum data rate of 1 Mbps. The device operates within a supply voltage range of 3 V to 5.5 V and offers an isolation voltage rating of 2500 Vrms. Key electrical specifications include a propagation delay of 100 ns and a common-mode transient immunity of 25 kV/µs. It is housed in a 16-SOIC package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates an isolated dc-to-dc converter for simplified power delivery across the isolation barrier
• Provides four independent bidirectional or unidirectional data channels for complex system interfacing
• Utilizes iCoupler magnetic coupling technology for high reliability and low power consumption

Applications

• Industrial automation systems requiring robust galvanic isolation
• Medical equipment needing certified safety isolation barriers
• Power metering applications with high-voltage sensing requirements

Procurement Notes

Verify the specific suffix (RL) indicates reel packaging when ordering. Confirm that the integrated DC/DC converter meets the target application's efficiency and noise requirements. Ensure the SOIC-16 footprint matches the PCB design. Check for RoHS compliance status as per current manufacturing standards. Validate availability through authorized distributors due to potential supply constraints.

Selection Notes

Select this component when a single IC solution is needed for both data isolation and isolated power generation. Compare against discrete solutions to evaluate board space savings versus potential thermal management needs. Consider the 1 Mbps data rate limit for high-speed communication alternatives. Verify that the 2500 Vrms isolation rating satisfies the specific safety standards required by the end product.

Part Context

This part belongs to the ADuM540x family of quad-channel digital isolators. It shares the same physical package and basic isolation architecture with variants like the ADUM5401 and ADUM5402, which differ primarily in data rate capabilities and channel configurations. The family represents Analog Devices' iCoupler technology implementation for general-purpose isolation tasks.

Replacement Considerations

Direct substitutes include the ADUM5401ARWZ-RL for higher speed requirements or the ADUM5402ARWZ-RL for different channel configurations. Cross-reference pinouts and thermal characteristics carefully when swapping between these family members.
