ADUM1411ARWZ-RL

Overview

The ADUM1411ARWZ-RL is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 3750Vrms isolation with a data rate of 1Mbps and 25kV/µs common-mode transient immunity. The device operates on a 2.7V to 5.5V supply, features unidirectional channels (3 inputs on side 1, 1 input on side 2), and has a maximum propagation delay of 100ns. It is housed in a 16-SOIC package and supports an operating temperature range of -40°C to 105°C.

Feature Summary

• Integrates four independent digital isolation channels using monolithic air core transformer technology for high-speed signal transmission.
• Provides robust noise immunity with a minimum common-mode transient immunity rating of 25kV/µs across all channels.
• Eliminates the need for external isolation components by combining high-speed CMOS logic with magnetic coupling on a single chip.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral interfaces.
• Medical equipment needing reliable signal separation for patient safety and noise reduction.
• Power electronics control circuits isolating gate drivers from low-voltage logic controllers.

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when ordering. Confirm that the 16-SOIC footprint matches the target PCB layout. Ensure the 1Mbps speed requirement aligns with system timing constraints. Check RoHS compliance status for regulatory adherence. Validate the 3750Vrms isolation voltage against application safety standards.

Selection Notes

Select this component when four isolated channels are required at moderate speeds up to 1Mbps. Consider the 3750Vrms isolation barrier for standard industrial applications. Evaluate the 100ns propagation delay for timing-sensitive designs. Compare power consumption against other iCoupler variants if battery life is critical. Verify the 16-SOIC package availability for assembly processes.

Part Context

This part belongs to the ADuM141x series of quad-channel digital isolators from Analog Devices. It shares the iCoupler architecture with related models like the ADUM1410 and ADUM1412, differing primarily in channel configuration and directionality. The series leverages silicon dioxide insulation layers for reliable long-term performance.

Replacement Considerations

The ADUM1410ARWZ-RL offers similar specifications but with a different channel configuration (4/0 vs 3/1). Verify pin compatibility before substitution. Other iCoupler devices may require level shifting or have different isolation ratings.
