ADUM5400CRWZ-RL

Overview

The ADUM5400CRWZ-RL is a quad-channel digital isolator from Analog Devices, featuring an integrated DC-to-DC converter. It provides four unidirectional signal channels with a data rate of 25 Mb/s and isolation voltage of 2500 Vrms. The device operates on a supply voltage range of 3 V to 5.5 V, with a maximum propagation delay of 60 ns. It is housed in a 16-lead SOIC package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates a high-efficiency DC-to-DC converter for isolated power delivery
• Provides four independent unidirectional signal channels
• Utilizes iCoupler magnetic coupling technology for signal transmission

Applications

• Industrial process control systems
• Medical equipment requiring galvanic isolation
• Power metering and energy management interfaces

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when ordering. Confirm RoHS compliance status through official documentation. Ensure the design accommodates the thermal requirements associated with the integrated DC/DC converter. Check for any recent process change notifications regarding assembly sites or materials.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required alongside integrated power conversion. Compare against the ADUM5401 if channel directionality differs. Consider the ADUM6400 for higher isolation voltage ratings. Evaluate power dissipation limits within the SOIC-16 package for the specific application load.

Part Context

This part belongs to the ADuM540x family of isoPower digital isolators. It combines signal isolation with power isolation in a single package. The series is designed to reduce solution size and complexity by eliminating external isolated power supplies. It complements other ADUM devices offering varying channel counts and isolation levels.

Replacement Considerations

The ADUM5401CRWZ-RL is a direct functional substitute within the same family. Verify channel directionality configurations match between parts. Ensure pinout compatibility remains identical for board-level replacement.
