ADUM6424ABRNZ5-RL

Overview

The ADUM6424ABRNZ5-RL is a four-channel digital isolator from Analog Devices, utilizing isoPower technology to provide an isolated data path and integrated power supply up to 5 kV. It operates with a unidirectional data configuration (0:4) on a single side, supporting a data rate of 100 Mb/s. The device features a propagation delay of 10 ns and pulse width distortion of 1 ns. It functions within a supply voltage range of 4.5 V to 5.5 V, drawing 9.6 mA of operating current. The component is housed in a 28-lead SOIC package and supports a shutdown function. It is rated for operation between -40°C and +125°C.

Feature Summary

• Integrates isoPower technology for combined signal isolation and isolated power delivery

Procurement Notes

Verify the specific suffix '5-RL' against official Analog Devices documentation to confirm reel packaging and tape specifications. Ensure the part number matches the exact datasheet revision for the ADUM6424A series. Confirm that the 28-lead SOIC footprint aligns with your PCB design requirements before finalizing procurement orders.

Selection Notes

Select this component when a quad-channel isolator with integrated isolated power is required. It is suitable for applications prioritizing low EMI emissions and high data rates up to 100 Mb/s. Consider the 0:4 channel configuration if all inputs are on one side. Verify thermal dissipation capabilities within the specified temperature range for your enclosure design.

Part Context

This part belongs to the ADUM6424A family of digital isolators. It shares the same core architecture as other variants in the series but differs in channel directionality and packaging. The ADUM6424A series is designed to replace optocouplers in many applications, offering superior speed and reliability while maintaining high isolation voltages.

Replacement Considerations

Direct substitutes include other ADUM6424A variants with different channel configurations or packaging options. Cross-reference with ADUM6423ABRNZ3 for similar performance with different voltage levels. Always verify pin compatibility and electrical parameters before substituting.
