ADUM6403ARIZ

Overview

The ADUM6403ARIZ is a quad-channel digital isolator from Analog Devices, featuring integrated isoPower isolated DC/DC converters. It provides galvanic isolation with a maximum insulation voltage of 5000 Vrms and an 8mm creepage distance. The device supports data rates up to 25 Mb/s with a propagation delay of 60 ns. It operates within a supply voltage range of 3 V to 5.5 V and functions across a temperature range of -40°C to +105°C. Packaged in a 16-pin SOIC, it combines four signal channels with internal power conversion for efficient system design.

Feature Summary

• Integrates isoPower technology for on-chip isolated DC/DC conversion
• Provides high-voltage galvanic separation via magnetic coupling
• Supports unidirectional data transmission across four independent channels

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing certified galvanic separation
• Power electronics control circuits with high common-mode noise

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check current availability as supply may be limited. Ensure storage conditions meet humidity requirements to prevent package damage before reflow soldering.

Selection Notes

Select this component when high channel density and integrated isolated power are required in a single package. Consider the 8mm creepage distance for safety clearance needs. Evaluate the 25 Mb/s data rate against system timing requirements. Verify that the 16-pin SOIC footprint fits the PCB layout constraints.

Part Context

This part belongs to the ADUM6403 series of digital isolators. It utilizes iCoupler technology for signal transmission. The series is designed for applications demanding reliable isolation between microcontrollers and peripheral devices. It replaces discrete isolation components and external power supplies to reduce board space.

Replacement Considerations

Check for pin-compatible alternatives within the same family. Verify if updated revisions offer improved performance metrics. Ensure substitute parts maintain the same insulation voltage and creepage distances.
