ADUM3472WARSZ-RL7

Overview

The ADUM3472WARSZ-RL7 is a four-channel digital isolator from the Analog Devices ADUM3472 series, manufactured by Analog Devices Inc. It utilizes magnetic coupling technology to provide electrical isolation between circuits. The device features bidirectional data transmission with a data rate of 25 Mb/s and an insulation voltage rating of 2500 Vrms. It operates within a supply voltage range of 3 V to 5.5 V and supports a propagation delay of 60 ns. The component is designed for industrial applications, operating reliably in temperatures ranging from -40°C to +105°C. It is housed in an SSOP-20 package and meets AEC-Q100 qualification standards for automotive use.

Feature Summary

• Integrates four independent bidirectional channels for high-density signal isolation
• Employs on-chip transformer technology for robust magnetic coupling isolation
• Includes integrated transformer drivers to minimize external component requirements
• Qualified for automotive applications under AEC-Q100 standards

Applications

• Automotive electronic control units requiring isolated communication
• Industrial automation systems with high-voltage noise environments
• Medical equipment needing galvanic isolation for safety compliance
• Power electronics interfaces for motor drives and inverters

Procurement Notes

Verify the specific suffix WARSZ-RL7 against official Analog Devices documentation to confirm package type, temperature grade, and reel specifications. Ensure compatibility with existing PCB footprints for the SSOP-20 form factor. Confirm that the AEC-Q100 qualification aligns with target automotive or industrial reliability requirements before finalizing procurement decisions.

Selection Notes

Select this component when four isolated bidirectional channels are required in a compact SSOP-20 footprint. It is suitable for designs needing 2500 Vrms isolation with 25 Mb/s data throughput. Consider the AEC-Q100 qualification if the application demands automotive-grade reliability. Evaluate power consumption and thermal performance within the specified -40°C to +105°C operating range.

Part Context

This part belongs to the ADUM347x family of digital isolators, which integrates isolation barriers directly onto the silicon die. The ADUM3472 variant specifically offers four bidirectional channels. The 'W' indicates wide body packaging, while 'AR' denotes the commercial/industrial temperature range and lead-free composition. The '-RL7' suffix specifies the tape and reel packaging format for automated assembly.

Replacement Considerations

Cross-reference with other ADUM347x variants such as ADUM3470, ADUM3471, ADUM3473, or ADUM3474 for channel directionality differences. Verify pinout compatibility and isolation voltage ratings when substituting with non-Analog Devices parts.
