ADUM3441CRWZ

Overview

The ADUM3441CRWZ is a quad-channel high-speed digital isolator from Analog Devices, housed in a 16-pin SOIC package. It operates on a single power supply ranging from 3 V to 5.5 V with a typical quiescent current of 1.3 mA per channel. The device supports bidirectional data transmission at speeds up to 150 Mb/s and provides an isolation voltage rating of 2500 Vrms via magnetic coupling technology. Key timing parameters include a propagation delay of 32 ns and rise/fall times of 3 ns. It functions within a temperature range of -40°C to +105°C.

Feature Summary

• Quad-channel architecture for simultaneous signal isolation
• Bidirectional data transmission capability
• Magnetic coupling isolation technology
• High-speed operation up to 150 Mb/s

Applications

• Industrial communication systems
• General-purpose digital signal isolation
• Isolated gate driver circuits
• Data acquisition systems

Procurement Notes

Verify the specific suffix (e.g., -RL) against your reel or cut-tape requirements, as packaging variants exist. Confirm the component status, as availability may be limited or subject to discontinuation notices. Ensure the SOIC-16 footprint matches your PCB design constraints before finalizing procurement decisions.

Selection Notes

Select this component when four isolated channels are required for high-speed bidirectional communication. Compare against the ADUM3440 if unidirectional flow is sufficient, or the ADUM3442 if specific pinout compatibility with other family members is needed. Consider the integrated DC/DC options in the ADUM54xx series if onboard isolation power generation is preferred over external supplies.

Part Context

This part belongs to the ADuM344x family of quad-channel digital isolators. It shares the same physical package and general electrical characteristics with siblings like the ADUM3440 and ADUM3442. The primary distinction lies in the internal logic directionality and specific pin configurations relative to other interface standards within the broader Analog Devices isolation portfolio.

Replacement Considerations

The ADUM3440CRWZ serves as a functional substitute if unidirectional isolation meets system requirements. For identical quad-channel bidirectional performance, verify the ADUM3442CRWZ for potential pin-compatible upgrades or legacy replacements.
