ADUM5404ARWZ-RL

Overview

The ADUM5404ARWZ-RL is a quad-channel digital isolator from Analog Devices, featuring an integrated DC-to-DC converter. It provides four independent isolation channels with unidirectional signal transmission at data rates up to 25 Mb/s. The device operates within a supply voltage range of 3 V to 5.5 V and offers an insulation voltage of 2500 Vrms using magnetic coupling technology. Key electrical parameters include a propagation delay of 60 ns, a typical operating supply current of 19 mA, and a maximum power dissipation of 500 mW. It supports an extended industrial temperature range from -40°C to +105°C and is housed in a 16-pin SOIC package.

Feature Summary

• Integrates a high-efficiency DC-to-DC converter to generate isolated power for the secondary side, eliminating the need for external isolated supplies.
• Provides robust galvanic isolation via magnetic coupling technology to protect sensitive circuitry from high-voltage transients.
• Supports high-speed digital communication with data rates up to 25 Mb/s across all four independent channels.

Applications

• Industrial automation systems requiring isolated sensor interfaces
• Medical equipment needing reinforced safety isolation
• Power electronics control circuits with ground potential differences

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance and moisture sensitivity levels prior to assembly. Ensure storage conditions meet humidity requirements to prevent package damage. Validate that the reel packaging matches specific handling protocols for surface-mount placement.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required alongside integrated power generation. Compare against the ADUM5404CRWZ variant if tube packaging is preferred over reel. Consider the ADUM6404 series if higher insulation voltage ratings are necessary for the application environment.

Part Context

This part belongs to the ADUM5404 series of quad-channel digital isolators. It shares the same functional architecture as the ADUM5404CRWZ but differs in packaging format and potentially manufacturing site specifications. The series utilizes Analog Devices' proprietary iCoupler technology for compact, high-performance isolation solutions.

Replacement Considerations

The ADUM5404CRWZ serves as a direct functional substitute with identical electrical characteristics, differing primarily in tube packaging instead of reel. Verify pinout compatibility and thermal performance before substitution.
