ADUM3480ARSZ

Overview

The ADUM3480ARSZ is a small, quad-channel digital isolator from Analog Devices. It provides four unidirectional channels with a typical propagation delay of 25 ns and supports data rates up to 25 Mbps (NRZ). The device operates on supply voltages ranging from 1.8 V to 5 V and offers level translation capabilities. It features high temperature operation and utilizes magnetic isolation technology with an isolation voltage rating of 3.75 kV RMS.

Feature Summary

• Provides four unidirectional signal paths for isolated data transmission
• Supports low dynamic power consumption for energy-efficient designs
• Enables level translation between 1.8 V and 5 V domains
• Utilizes proprietary magnetic isolation technology for robust performance

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power metering applications with high voltage isolation needs

Procurement Notes

Verify the specific suffix ARSZ corresponds to the SOIC-16 package when ordering. Confirm that the required isolation voltage rating of 3.75 kV RMS meets your system safety standards. Ensure compatibility with the 1.8 V to 5 V operating voltage range for both sides of the isolator before finalizing procurement.

Selection Notes

Select this component when four independent unidirectional channels are required within a compact footprint. It is suitable for applications demanding low propagation delay and high data throughput up to 25 Mbps. Consider the 3.75 kV RMS isolation barrier for noise immunity in electrically noisy environments.

Part Context

This part belongs to the ADUM34xx series of digital isolators from Analog Devices. These devices are designed to replace traditional optocouplers, offering superior performance in terms of speed, power consumption, and reliability. The series supports various channel configurations and isolation ratings for diverse industrial and commercial applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADUM34xx family if different channel directionality or isolation ratings are needed. Verify that any substitute maintains the 3.75 kV RMS isolation voltage and 25 Mbps data rate specifications.
