ADUM6402ARIZ

Overview

The ADUM6402ARIZ is a quad-channel digital isolator from Analog Devices, housed in a 16-lead SOIC package. It features integrated isoPower technology with an on-chip DC-to-DC converter, eliminating the need for external isolated power supplies. The device supports data rates up to 25 Mb/s and offers 5000 Vrms isolation voltage with 8mm creepage distance. It operates within a supply voltage range of 3V to 5.5V and functions across temperatures from -40°C to +105°C. Key electrical parameters include a propagation delay of 60 ns and common-mode transient immunity of 25 kV/µs.

Feature Summary

• Integrates isoPower technology with an on-chip DC-to-DC converter for simplified system design
• Provides robust magnetic coupling isolation with high common-mode transient immunity
• Supports unidirectional signal transmission across four independent channels

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix (ARIZ) against official Analog Devices documentation to confirm temperature grade and packaging details. Ensure compatibility with existing PCB footprints for the 16-SOIC package. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a quad-channel isolator with integrated isolated power is required. It is suitable for applications demanding high reliability and reduced bill-of-materials complexity. Consider the 25 Mb/s data rate and 5000 Vrms isolation rating against system requirements.

Part Context

This part belongs to the ADuM640x family of quad-channel digital isolators. The series is designed to replace traditional optocouplers in modern electronic designs, offering superior performance in speed, power consumption, and size. The ADUM6402 variant specifically integrates the power conversion stage on the secondary side.

Replacement Considerations

Check for direct pin-compatible substitutes within the ADuM640x family, such as the ADUM6401 or ADUM6403, depending on channel directionality needs. Verify that any replacement maintains the same isoPower integration and isolation voltage ratings.
