ADUM6424ABRNZ3-RL

Overview

The ADUM6424ABRNZ3-RL is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC-to-DC converter. It provides four data channels with a 0:4 configuration and operates at a data rate of 100 Mb/s. The device supports a supply voltage range of 3 V to 3.6 V on the primary side and 3 V to 5.5 V on the secondary side. It offers an insulation voltage of 500 Vrms and a propagation delay of 10 ns. Packaged in a SOIC-28 surface-mount format, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates an isolated DC-to-DC converter for power delivery across the isolation barrier
• Provides low electromagnetic interference (EMI) performance for signal integrity
• Includes a shutdown pin for active power management control

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment with safety isolation requirements
• Data acquisition modules needing high-speed signal transmission

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package marking and date codes match official specifications. Check for restricted availability status as indicated by current supply constraints. Ensure storage conditions comply with moisture sensitivity levels prior to assembly.

Selection Notes

Select this part when a 0:4 channel configuration is required alongside integrated isolated power. Compare against the ADUM6424ABRNZ5-RL if a 5V primary supply is preferred instead of 3V. Evaluate thermal dissipation capabilities given the 2.78 W power handling specification in the SOIC-28 package.

Part Context

This component belongs to the ADuM642xA family of quad-channel digital isolators. It shares architectural similarities with the ADUM6421A series but differs in channel directionality and power supply configurations. The evaluation kit EVAL-ADUM6421A is referenced for development support.
