ADUM1411ARWZ

Overview

The ADUM1411ARWZ is a four-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 3750Vrms isolation voltage with a data rate of 1Mbps and common-mode transient immunity of 25kV/µs. The device operates on a supply voltage range of 2.7V to 5.5V, featuring unidirectional channels configured as three inputs on side 1 and one input on side 2. It is housed in a 16-SOIC package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates four independent digital isolation channels within a single compact package.
• Employs iCoupler technology to eliminate the need for external isolation transformers.
• Provides high common-mode transient immunity for reliable signal transmission in noisy environments.

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment signal interfaces
• Power management circuit monitoring

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm packaging configuration and revision status. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Selection Notes

Select this component when four isolated digital channels are required with moderate speed capabilities. The unidirectional channel configuration suits applications where data flows primarily in one direction across the isolation barrier. Consider the 16-SOIC footprint for PCB layout constraints and verify that the 1Mbps data rate aligns with system timing requirements.

Part Context

This part belongs to the ADuM141x series of general-purpose digital isolators. The series leverages silicon dioxide insulation layers to achieve high isolation performance while maintaining low power consumption compared to traditional optocoupler solutions.

Replacement Considerations

Consult official substitution guides for equivalent parts within the ADuM141x family or other iCoupler-based isolators. Verify pin compatibility and electrical specifications before replacing existing components in established designs.
