ADUM1401WSRWZ35

Overview

The ADUM1401WSRWZ35 is a quad-channel digital isolator utilizing iCoupler technology, housed in a 16-lead SOIC package. It supports bidirectional communication with 3V/5V level translation and operates within a supply voltage range of 2.7V to 5.5V. The device provides high data rates up to 90 Mbps (NRZ) with precise timing characteristics, including a maximum propagation delay of 32 ns and channel-to-channel matching of 2 ns. It features a minimum common-mode transient immunity of 25 kV/µs and an isolation voltage rating of 2500 Vrms. Qualified for automotive applications under AEC-Q100 standards, it functions reliably across an extended temperature range from -40°C to 125°C.

Feature Summary

• Bidirectional communication capability with integrated 3V/5V level translation
• High common-mode transient immunity exceeding 25 kV/µs
• Automotive qualification compliant with AEC-Q100 standards
• Extended operating temperature range supporting -40°C to 125°C

Applications

• General-purpose multichannel isolation
• SPI interface and data converter isolation
• RS-232/RS-422/RS-485 transceivers
• Industrial field bus isolation
• Automotive systems

Procurement Notes

Verify the specific suffix '35' against official Analog Devices documentation to confirm moisture sensitivity level and reel specifications. Ensure compatibility with existing board layouts regarding the 16-lead SOIC wide body package dimensions. Cross-reference the AEC-Q100 qualification status if automotive reliability is required for the final assembly.

Selection Notes

Select this component when bidirectional signal transfer is required alongside robust noise immunity. The 90 Mbps data rate suits high-speed interfaces like SPI. Consider the 2500 Vrms isolation barrier for safety-critical designs. Verify power consumption requirements at target data rates, as current draw increases significantly at higher frequencies compared to lower speed alternatives.

Part Context

This part belongs to the ADuM140x series of quad-channel digital isolators. It shares architectural similarities with the ADUM1400 and ADUM1402 but differs in channel configuration and directionality. The series leverages monolithic air core transformer technology to replace traditional optocouplers, offering superior performance in size, speed, and reliability.
