ADUM4401CRIZ-RL

Overview

The ADUM4401CRIZ-RL is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. The device provides an insulation voltage of 5000 Vrms and features enhanced ESD protection with a common-mode transient immunity of 25 kV/µs. Packaged in a 16-pin SOIC (0.295 inch width) format, it functions unidirectionally with a typical propagation delay of 32 ns and rise/fall times of 3 ns. It is rated for operation between -40°C and +105°C.

Feature Summary

• Integrates four independent isolation channels using proprietary magnetic coupling architecture.
• Provides enhanced electrostatic discharge protection for robust signal integrity.
• Supports high common-mode transient immunity to maintain performance in noisy environments.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal interfaces
• Power electronics control circuits

Procurement Notes

Verify the specific suffix 'CRIZ' against official Analog Devices documentation to confirm package dimensions and moisture sensitivity level. Ensure the reel quantity matches project requirements. Confirm RoHS compliance status through current datasheets as specifications may evolve. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required in a compact footprint. Consider the 90 Mb/s data rate limit and 5000 Vrms isolation barrier for system design. Evaluate the 16-SOIC package constraints against PCB layout space. Compare power consumption characteristics against alternative isolators if energy efficiency is critical.

Part Context

This part belongs to the ADUM4401 series of digital isolators. It shares functional similarities with other members like the ADUM4401ARWZ-RL but differs in packaging and potentially qualification grades. The series is designed for general-purpose isolation applications where high reliability and small size are prioritized over extreme speed or higher channel counts.

Replacement Considerations

Check for direct pin-compatible substitutes such as the ADUM4401ARWZ-RL. Verify that any replacement maintains the same 16-SOIC package and electrical parameters including 90 Mb/s speed and 5000 Vrms rating before implementation.
