ADUM1401WSRWZ

Overview

The ADUM1401WSRWZ is a unidirectional digital isolator from Analog Devices, featuring four channels with a configuration of three transmitters and one receiver. It utilizes magnetic coupling technology to provide an isolation voltage of 2500 Vrms and supports data rates up to 90 Mb/s. The device operates within a supply voltage range of 2.7 V to 5.5 V and exhibits a propagation delay of 100 ns. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Unidirectional signal transmission architecture with mixed channel configuration
• High common-mode transient immunity via magnetic coupling technology
• Automotive-grade qualification ensuring reliability in harsh environments

Applications

• Fully isolated analog output modules
• Power line monitoring systems
• Industrial communication interfaces requiring galvanic isolation

Procurement Notes

Verify the specific suffix designation against official documentation to confirm packaging format, as variants exist for reel or tube configurations. Ensure that the selected part number aligns with the required channel directionality and supply voltage specifications for the target application design.

Selection Notes

Select this component when unidirectional isolation is sufficient for the system architecture. Compare power consumption metrics against other family members if low-power operation is critical, noting that current draw varies based on the active channel count and data rate requirements.

Part Context

This part belongs to the ADUM1401 series, which offers various channel configurations including all-transmitter and mixed setups. It shares the same core iCoupler technology and package dimensions as related models like the ADUM1400 and ADUM1402, differing primarily in internal channel routing and directionality.

Replacement Considerations

The ADUM1401WTRZ-RL serves as a direct replacement variant offering identical electrical performance but packaged in tape-and-reel format instead of the standard tube.
