ADUM4401WARWZ-RL

Overview

The ADUM4401WARWZ-RL is a quad-channel digital isolator utilizing magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. The device provides an insulation voltage of 5000 Vrms with unidirectional signal transmission. Key electrical parameters include a propagation delay of 32 ns, a quiescent current of 830 uA, and an operating temperature range from -40°C to +105°C. It is AEC-Q100 qualified and housed in a 16-pin SOIC package.

Feature Summary

• Integrates four independent isolation channels using proprietary magnetic coupling architecture for high-speed data transfer.
• Features enhanced ESD protection capabilities alongside robust galvanic isolation performance.
• Supports bidirectional power delivery through integrated isolated DC/DC converter options in the broader family context, though this specific part focuses on signal isolation.

Applications

• Industrial automation systems requiring reliable signal isolation
• Medical equipment needing enhanced safety isolation standards
• Automotive electronics compliant with AEC-Q100 qualification

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the received parts match the specified package type and marking codes. Check for any recent product change notices regarding assembly sites or material composition updates. Ensure storage conditions comply with moisture sensitivity level requirements before soldering.

Selection Notes

Select this component when high channel density and low power consumption are critical. The unidirectional configuration suits applications where signal flow is strictly one-way. Consider the 90 Mb/s speed limit against system timing requirements. Evaluate the 5000 Vrms isolation rating against circuit voltage potentials to ensure adequate safety margins.

Part Context

This part belongs to the ADUM4401 series of digital isolators manufactured by Analog Devices. It is designed for applications demanding high reliability and noise immunity. The series leverages iCoupler technology to provide compact, cost-effective isolation solutions compared to traditional optocouplers.

Replacement Considerations

Direct substitutes may include other quad-channel digital isolators from Analog Devices such as the ADUM4224 series for gate driver applications, or the ADUM3401 for bidirectional needs. Verify pinout compatibility and isolation voltage ratings before substitution.
