ADUM6424ABRNZ3

Overview

The ADUM6424ABRNZ3 is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC-to-DC converter. It operates with a 3V supply voltage (range 3V to 3.6V) and supports data rates up to 100 Mb/s. The device provides 500 Vrms insulation voltage and offers common-mode transient immunity of 75 kV/µs. Key electrical parameters include a propagation delay of 10 ns and a pulse width distortion of 1 ns. It functions within a temperature range of -40°C to +125°C and dissipates up to 2.78 W. The component is housed in a 28-pin SOIC package.

Feature Summary

• Integrates an isolated DC-to-DC converter for power delivery across the isolation barrier
• Provides four independent bidirectional data channels for high-speed communication
• Features low electromagnetic interference characteristics suitable for sensitive applications

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal transmission across isolation barriers
• Power electronics monitoring and control interfaces

Procurement Notes

Verify current availability status as supply may be limited or restricted. Confirm that the specific suffix indicates the 3V operating voltage variant. Ensure compatibility with existing 28-pin SOIC footprints during integration. Check for any recent product change notifications regarding pinout or electrical specifications before finalizing procurement plans.

Selection Notes

Select this component when a quad-channel isolator with integrated power conversion is required. It is appropriate for designs needing 3V operation on the secondary side. Consider the 100 Mb/s data rate limit for bandwidth requirements. Evaluate thermal management needs due to the specified power dissipation capabilities in the SOIC package.

Part Context

This part belongs to the ADuM642xA family of quad-channel digital isolators. These devices are designed to replace traditional transformer and optocoupler-based solutions. They offer improved performance in terms of speed, reliability, and size reduction. The family includes variants for different voltage domains, such as the 5V version.

Replacement Considerations

The ADUM6424ABRNZ5 serves as a direct alternative for designs requiring 5V operation instead of 3V. Both parts share identical pinouts, channel counts, and core isolation features. Verify voltage domain compatibility before substitution.
