ADUM1411BRWZ

Overview

The ADUM1411BRWZ is a quad-channel digital isolator based on Analog Devices iCoupler technology. It combines high-speed CMOS and monolithic air-core transformer technology to provide robust signal isolation. The device supports data rates up to 10 Mbps (NRZ) and offers a common-mode transient immunity of 25 kV/µs. It operates with supply voltages of 3 V or 5 V, consuming a maximum of 1.3 mA per channel at 5 V for data rates between 0 and 2 Mbps. The component is housed in a 16-pin SOIC package.

Feature Summary

• Integrates four independent digital isolation channels using proprietary iCoupler technology
• Provides bidirectional communication capability for digital interfaces
• Supports voltage level translation between 3 V and 5 V domains
• Features high common-mode transient immunity for noise-sensitive environments

Applications

• Isolation for general-purpose digital communication interfaces
• Industrial systems requiring galvanic isolation
• Medical equipment signal conditioning
• Power management circuit monitoring

Procurement Notes

Verify the specific suffix (e.g., BRWZ vs. BRWZ-RL) against official Analog Devices documentation to confirm packaging type and reel specifications. Ensure the procurement source provides valid manufacturer traceability. Cross-reference the ordering part number with the latest datasheet revision to confirm pinout compatibility and electrical ratings before finalizing orders.

Selection Notes

Select this component when four isolated channels are required within a single package footprint. It is suitable for applications needing moderate data rates up to 10 Mbps. Consider the 16-SOIC package dimensions for PCB layout constraints. Verify that the required isolation voltage rating meets the system's safety standards and that the operating temperature range covers the intended environment.

Part Context

This part belongs to the ADuM141x family of quad-channel digital isolators from Analog Devices. These devices utilize magnetic coupling rather than optical or capacitive methods, offering long-term stability and reliability. The family is designed to replace traditional optocouplers in various industrial and commercial applications where size and power consumption are critical factors.

Replacement Considerations

Consult official Analog Devices substitution guides for verified equivalents. Generic cross-references may not match the specific iCoupler performance characteristics or pin configurations.
