ADUM6424ABRNZ5

Overview

The ADUM6424ABRNZ5 is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC-to-DC converter. It operates with a 5V supply on the primary side and provides four unidirectional data channels. The device supports a data rate of 100 Mb/s and offers an insulation voltage of 5000 Vrms. Key electrical parameters include a propagation delay of 10 ns, a pulse width distortion of 1 ns, and a shutdown function. It functions within a temperature range of -40°C to +125°C and is housed in a SOIC-28 package.

Feature Summary

• Integrates an isolated DC-to-DC converter for simplified power delivery across isolation barriers
• Provides low electromagnetic interference (EMI) performance suitable for sensitive applications
• Includes a dedicated shutdown pin for active power management and energy conservation

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing high-voltage safety compliance
• Instrumentation interfaces demanding low EMI characteristics

Procurement Notes

Verify the specific suffix '5' indicates the reel packaging configuration when ordering. Confirm that the required voltage levels match the 5V primary side specification. Ensure the design accommodates the thermal dissipation requirements associated with the integrated converter. Check for RoHS compliance documentation prior to final procurement approval.

Selection Notes

Select this component when a quad-channel solution with integrated power conversion is necessary. It is appropriate for designs requiring 100 Mb/s data rates and 5000 Vrms isolation. Consider the SOIC-28 footprint for PCB layout constraints. Evaluate the 9.6 mA operating current against system power budgets.

Part Context

This part belongs to the ADuM642xA family of quad-channel digital isolators. These devices are designed to replace traditional transformer and optocoupler solutions in high-speed digital isolation applications. The family emphasizes compact size and reduced bill-of-materials through integrated power management.

Replacement Considerations

The ADUM6423ABRNZ3 serves as a related variant within the same family, offering similar isolation features but configured for different voltage domains.
