ADUM4401ARWZ-RL

Overview

The ADUM4401ARWZ-RL is a quad-channel digital isolator from Analog Devices, housed in a 16-lead SOIC_W package. It operates within a temperature range of -40°C to +105°C and supports unidirectional data transmission at speeds up to 90 Mb/s. The device provides an insulation voltage of 5000 Vrms with a common-mode transient immunity of 25 kV/µs. Key electrical parameters include a propagation delay of 32 ns, rise/fall times of 3 ns, and a pulse width distortion capability of 1000 ns. It functions on supply voltages between 2.7 V and 5.5 V.

Feature Summary

• Integrates four independent isolation channels for high-density signal transmission
• Features enhanced electrostatic discharge protection capabilities
• Utilizes magnetic coupling technology for reliable galvanic isolation

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing high-voltage safety barriers
• Power electronics control circuits

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm the manufacturer part number matches exactly to ensure compatibility with design specifications. Check current availability status as distribution may be limited. Ensure the component meets required environmental standards for the intended operating temperature range.

Selection Notes

Select this component when four isolated channels are required in a single package. Consider the 5000 Vrms insulation rating for high-voltage applications. Evaluate the 90 Mb/s data rate against system timing requirements. Compare power consumption and package size against alternative isolators if space or energy efficiency is critical.

Part Context

This part belongs to the ADuM440x series of digital isolators. It shares the SOIC-16 footprint with other variants like the ADUM4400 and ADUM4402. The series utilizes Analog Devices' iCoupler technology for compact, low-power isolation solutions suitable for demanding industrial environments.

Replacement Considerations

Direct substitutes include ADUM4400ARWZ-RL and ADUM4402ARWZ-RL from the same family. Verify channel count and speed specifications match before substitution. Cross-reference pinouts and insulation ratings to ensure functional equivalence.
