ADUM6402ARIZ-RL

Overview

The ADUM6402ARIZ-RL is a four-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features an integrated isoPower DC/DC converter providing 5000 Vrms isolation voltage and supports data rates up to 25 Mb/s with a propagation delay of 60 ns. The device operates within a supply voltage range of 3 V to 5.5 V and is housed in a 16-pin SOIC package with an 8 mm creepage distance. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Integrates a high-efficiency isolated DC/DC converter to provide power and signal isolation in a single package.
• Employs on-chip transformer technology to achieve robust magnetic coupling with high common-mode transient immunity.
• Offers bidirectional or unidirectional channel configurations to support diverse communication protocols.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors.
• Medical equipment interfaces needing certified safety isolation standards.
• Power electronics control circuits involving high-voltage switching environments.

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing. Confirm the 'A' grade designation matches required performance specifications. Check current availability status as distribution may be limited. Ensure compatibility with existing PCB footprints for the SOIC-16 package. Validate insulation clearance requirements against application safety standards.

Selection Notes

Select this component when both signal isolation and isolated power delivery are required simultaneously. Compare channel count and data rate requirements against alternative models in the ADUM640x series. Consider the thermal performance of the SOIC-16 package for your enclosure design. Evaluate the 5000 Vrms isolation rating against system voltage stresses. Verify operating temperature range suitability for the intended environment.

Part Context

This part belongs to the ADUM640x family of digitally controlled isolators. These devices combine analog signal paths with digital control loops for efficient power transfer. The series is designed to replace traditional optocouplers and discrete transformer solutions. It addresses space constraints in modern compact electronic designs.

Replacement Considerations

Check ADUM6403ARIZ-RL for similar specifications with potential pinout differences. Review ADUM6402CRIZ-RL for commercial grade alternatives if industrial ratings are not required. Consult official substitution guides for verified cross-references.
