ADUM6404ARWZ

Overview

The ADUM6404ARWZ is a four-channel digital isolator from Analog Devices, housed in a 16-pin SOIC package. It features integrated DC/DC converters for power isolation and supports data rates up to 25 Mb/s with a propagation delay of 60 ns. The device provides 5000 Vrms insulation voltage and operates within a supply voltage range of 3 V to 5.5 V. It exhibits a common-mode transient immunity of 25 kV/µs and functions reliably across an industrial temperature range of -40°C to +105°C.

Feature Summary

• Integrates on-chip DC/DC converters to provide isolated power supplies for both sides of the isolation barrier.
• Utilizes magnetic coupling technology to achieve high-voltage electrical isolation between input and output channels.
• Offers high common-mode transient immunity to maintain signal integrity in electrically noisy environments.

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing galvanic isolation for safety compliance
• Power metering applications involving high-voltage measurement

Procurement Notes

Verify the specific suffix (e.g., RL) against official documentation to confirm packaging type such as reel or cut tape. Ensure the operating voltage and isolation requirements match the system design before procurement. Check for RoHS compliance status and moisture sensitivity levels during storage planning.

Selection Notes

Select this component when high channel count and integrated power isolation are required in a compact SOIC-16 footprint. Compare the 5000 Vrms rating against lower-rated alternatives if space permits. Consider the 25 Mb/s data rate limit for high-speed communication needs.

Part Context

This part belongs to the ADUM6404 series of general-purpose digital isolators. It is designed to replace optocouplers in many applications, offering superior performance in speed, power consumption, and size. The series is widely used in industrial and medical fields where reliable isolation is critical.

Replacement Considerations

Check for direct substitutes like the ADUM5404ARWZ, which offers similar functionality but with a lower 2500 Vrms isolation rating. Verify pin compatibility and thermal characteristics when considering alternative models from the same manufacturer.
