ADUM6402CRIZ

Overview

The ADUM6402CRIZ is a quad-channel digital isolator from Analog Devices, featuring an integrated DC/DC converter for power delivery across the isolation barrier. It provides 5000 Vrms insulation strength and supports data rates up to 25 Mb/s with a common-mode transient immunity of 25 kV/µs. The device operates within a supply voltage range of 3 V to 5.5 V and offers propagation delays as low as 45 ns. Packaged in a 16-pin SOIC (Wide) housing, it ensures reliable signal transmission in electrically noisy environments.

Feature Summary

• Integrates a high-efficiency DC/DC converter to provide isolated power without external magnetics
• Provides robust electrical isolation with 5000 Vrms rating and 8 mm creepage distance
• Delivers high-speed data transmission at 25 Mb/s with superior common-mode transient immunity

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power electronics control circuits with high noise susceptibility

Procurement Notes

Verify the specific suffix 'CRIZ' against official Analog Devices documentation to confirm package type and temperature grade. Confirm current availability status as distribution channels may list limited stock or obsolete status. Ensure compliance with RoHS directives and moisture sensitivity levels prior to assembly planning.

Selection Notes

Select this component when a single-chip solution for both signal isolation and isolated power generation is required. It is suitable for designs needing four independent channels with bidirectional or unidirectional flexibility depending on the variant. Consider the 16-SOIC footprint for PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the ADUM6402 series of general-purpose digital isolators. It utilizes capacitive coupling technology combined with on-board DC/DC conversion to replace traditional optocouplers and magnetic transformers. The series is designed for applications demanding high reliability and long-term stability in harsh industrial conditions.

Replacement Considerations

Check for direct pin-compatible substitutes within the ADUM64xx family. Verify that alternative components support the same 5000 Vrms isolation rating and integrated power functionality. Ensure the replacement matches the 16-SOIC package dimensions and operating temperature range.
