ADUM1411BRWZ-RL

Overview

The ADUM1411BRWZ-RL is a quad-channel digital isolator based on Analog Devices iCoupler technology. It provides 3750Vrms isolation with a data rate of 10Mbps and 25kV/µs CMTI. The device operates on 2.7V to 5.5V supplies, features unidirectional channels (3/1 split), 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 isolation channels using monolithic air core transformer technology for robust signal transmission.
• Provides high common-mode transient immunity to protect against noise in electrically noisy environments.
• Supports standard logic voltage levels across a wide supply voltage range for flexible system integration.

Applications

• Industrial automation systems requiring galvanic isolation between control and power stages.
• Medical equipment needing reliable signal isolation for patient safety compliance.
• Power metering applications involving high-voltage sensing and data acquisition.

Procurement Notes

Verify the specific suffix RL indicates reel packaging when ordering. Confirm the BRWZ variant matches the required 10Mbps speed grade and 105°C temperature rating. Ensure the 16-SOIC footprint aligns with the PCB layout. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when four isolated channels are needed at moderate speeds. Compare against higher-speed variants like the ADUM141E1 series if greater bandwidth is required. Consider the 3/1 channel split configuration for asymmetric interface needs. Verify that the 3750Vrms isolation rating meets the system's safety requirements.

Part Context

This part belongs to the ADuM1400/1/2 family of quad-channel digital isolators. These devices utilize CMOS technology to replace traditional optocouplers. The family offers various speed grades and isolation ratings to suit different application constraints while maintaining a consistent pinout and package style.

Replacement Considerations

The ADUM1411ARWZ-RL is a lower-speed alternative within the same family. The ADUM141E1WBRWZ-RL offers higher performance metrics including increased data rates and improved transient immunity. Verify compatibility before substituting these parts.
