ADUM3441CRWZ-RL

Overview

The ADUM3441CRWZ-RL 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 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 multi-line signal isolation
• Bidirectional data flow capability across all channels
• Integrated magnetic coupling technology for galvanic isolation
• High-speed operation supporting data rates up to 150 Mb/s

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power electronics gate drive interfaces
• Instrumentation and measurement devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to the presence of obsolete status indicators in some listings. Confirm RoHS compliance details as specified in official documentation. Ensure storage conditions meet moisture sensitivity requirements prior to assembly. Validate pinout compatibility with existing PCB footprints before integration into new designs.

Selection Notes

Select this component when bidirectional communication is required across four isolated channels. Compare against unidirectional variants if directionality constraints exist. Evaluate power consumption requirements against the 1.3 mA per channel specification. Consider thermal management needs given the operating temperature range and package type. Verify insulation voltage ratings match system safety standards.

Part Context

This part belongs to the ADuM344x series of iCoupler digital isolators. It shares the SOIC-16 footprint with related models like ADUM3440 and ADUM3442 but differs in channel directionality and specific electrical characteristics. The series utilizes CMOS-SOI technology to integrate isolation barriers directly onto the silicon die.

Replacement Considerations

ADUM3440CRWZ-RL offers similar specifications but may differ in channel configuration or performance metrics. ADUM3442CRWZ-RL is another quad-channel option within the same family. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
