ADUM1400WSRWZ55

Overview

The ADUM1400WSRWZ55 is a four-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and provides an isolation voltage of 2500 Vrms. The device supports data rates up to 90 Mb/s with a maximum propagation delay of 100 ns. It features unidirectional signal transmission across four channels (4Tx/0Rx) in a 16-SOIC package. Certified under AEC-Q100 for automotive applications, it functions reliably between -40°C and +125°C.

Feature Summary

• Employs proprietary iCoupler magnetic coupling technology for robust signal isolation without optical or capacitive components.
• Provides high common-mode transient immunity of 25 kV/µs to maintain signal integrity in noisy environments.
• Offers four independent unidirectional channels for efficient multi-line data isolation in a compact surface-mount package.

Applications

• Automotive electronic control units requiring AEC-Q100 certified isolation
• Industrial communication interfaces such as RS-485 and CAN bus systems
• Medical equipment requiring reinforced galvanic isolation

Procurement Notes

Verify the specific suffix '55' against official Analog Devices documentation to confirm any unique manufacturing or testing specifications distinct from the standard ADUM1400WSRWZ variant. Confirm current availability status as distribution channels may list this part as limited supply or obsolete depending on regional inventory constraints.

Selection Notes

Select this component when four isolated unidirectional channels are required for automotive or industrial applications. Ensure the design accommodates the SOIC-16 footprint and thermal requirements for operation up to 125°C. Validate that the 2500 Vrms isolation rating meets the safety standards of the target system architecture.

Part Context

This part belongs to the ADUM1400 series of general-purpose digital isolators. It shares core architectural similarities with other members like the ADUM1400WTRWZ but differs in packaging configuration and specific commercial suffixes. The series is designed for cost-effective isolation solutions in high-volume consumer and industrial electronics.

Replacement Considerations

The ADUM1400WSRWZ serves as the primary tube-packaged equivalent. For reel-based procurement needs, the ADUM1400WSRWZ-RL is the direct functional substitute. Verify pinout compatibility before substitution.
