ADUM6404ARIZ-RL

Overview

The ADUM6404ARIZ-RL is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower DC-to-DC converter. It provides 5000 Vrms isolation voltage with magnetic coupling technology. The device supports data rates up to 25 Mb/s and operates within a supply voltage range of 3 V to 5.5 V. It exhibits a propagation delay of approximately 60 ns and functions reliably across an industrial temperature range of -40°C to +105°C. Packaged in a 16-pin SOIC (0.295 inch width) surface-mount format, it ensures high common-mode transient immunity.

Feature Summary

• Integrates a DC-to-DC converter for isolated power delivery, eliminating the need for external isolated supplies.
• Provides robust electrical isolation via magnetic coupling technology for signal integrity.
• Supports high-speed data transmission with low propagation delay characteristics.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safety-certified isolation barriers
• Inverters and motor drives for control signal isolation

Procurement Notes

Verify the specific suffix 'ARIZ' against your bill of materials to ensure correct package width and temperature rating. Confirm that the reel packaging aligns with your assembly line requirements. Cross-reference the datasheet revision date to ensure compatibility with current design specifications. Validate that the integrated DC/DC converter output meets the load requirements of your isolated side circuitry before finalizing procurement.

Selection Notes

Select this component when a quad-channel isolator with integrated power is required to simplify board layout. It is suitable for applications demanding high CMTI and reliable operation in noisy environments. Consider the 16-pin SOIC footprint constraints during PCB design. Ensure the input/output logic levels are compatible with the source and destination devices within the specified voltage ranges.

Part Context

This part belongs to the ADUM6404 series of general-purpose digital isolators. It shares the same functional architecture as the ADUM6404CRIZ but may differ in manufacturing lot or specific qualification standards. The series is designed to replace optocouplers in modern designs, offering superior performance in speed, power consumption, and size.

Replacement Considerations

The ADUM6404CRIZ-RL is a direct pin-compatible alternative within the same family. Verify if the 'C' variant meets the specific reliability or qualification requirements of your application. Both parts share identical electrical specifications and pinouts.
