ADUM2401ARIZ

Overview

The ADUM2401ARIZ is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology to provide galvanic isolation. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 1 Mb/s. The device features a propagation delay of 65 ns with rise and fall times of 3 ns. It offers an insulation voltage of 5000 Vrms and functions reliably across an operating temperature range of -40°C to +105°C. Packaged in a 16-pin SOIC format, it is designed for high-reliability signal transmission in noisy environments.

Feature Summary

• Provides four independent unidirectional signal channels for robust data isolation
• Employs on-chip dual-coil transformer technology for magnetic coupling isolation
• Ensures precise timing performance with low pulse width distortion and channel-to-channel matching

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics monitoring circuits demanding high common-mode transient immunity

Procurement Notes

Verify the specific suffix (ARIZ) against official Analog Devices documentation to confirm package type and temperature grade. Confirm RoHS compliance status through current datasheets. Check for moisture sensitivity level requirements during storage and handling. Ensure the source document matches the exact part number to avoid substitution errors.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required at 1 Mb/s speeds. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the SOIC-16 footprint constraints against PCB layout requirements. Compare power consumption figures if battery-operated designs are involved.

Part Context

This part belongs to the ADUM2401 series of quad-channel digital isolators. It shares the same core isolation architecture as other variants in the family but differs in packaging and temperature specifications. The ARIZ designation indicates a specific industrial-grade version in a narrow SOIC package.

Replacement Considerations

Cross-reference with ADUM2401ARWZ for wider SOIC options or ADUM2401CRIZ for commercial temperature grades. Verify pin compatibility and electrical parameters before substituting.
