ADUM6423ABRNZ3-RL

Overview

The ADUM6423ABRNZ3-RL is a quad-channel digital isolator from Analog Devices featuring integrated isoPower technology. It provides 5000Vrms isolation voltage with low EMI characteristics. The device supports data rates up to 100 Mb/s and operates on a single 3V supply (3V to 3.6V). Key electrical parameters include a propagation delay of 10 ns, pulse width distortion of 1 ns, and a maximum power dissipation of 2.78 W. It functions within a temperature range of -40°C to +125°C and utilizes an SOIC-28 package.

Feature Summary

• Integrates DC-to-DC converter for isolated power delivery
• Provides high-speed signal transmission at 100 Mb/s
• Features low electromagnetic interference design
• Includes shutdown control functionality

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment with safety isolation requirements
• Data acquisition systems with multiple isolated channels
• Power electronics monitoring interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to procurement. Check current availability as supply may be limited. Ensure storage conditions meet humidity sensitivity requirements specified in the datasheet. Validate packaging integrity upon receipt to prevent damage to the SOIC-28 package.

Selection Notes

Select this component when four isolated channels are required with integrated power conversion. Choose the 3V variant specifically for low-voltage logic interfaces. Consider the SOIC-28 package for board space constraints. Verify thermal management capabilities given the 2.78 W power dissipation rating. Ensure system timing requirements align with the 10 ns propagation delay specification.

Part Context

This part belongs to the ADUM6423 family of quad-channel isolators. It shares architectural similarities with other ADUM64xx series devices but differs in supply voltage configuration. The BRNZ suffix indicates specific pinout and packaging variations. Development tools like EVAL-ADUM6421A are available for testing related variants in the same product line.

Replacement Considerations
