ADUM1402WSRWZ

Overview

The ADUM1402WSRWZ is a unidirectional digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features four independent channels configured as two transmitters and two receivers. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. Key electrical specifications include an isolation voltage of 2500 Vrms, a propagation delay of 100 ns, and a typical rise/fall time of 2.5 ns. It is housed in a 16-pin SOIC-W package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Provides galvanic isolation between circuits using on-chip transformer-based magnetic coupling technology.
• Offers four independent signal paths with a configuration of two inputs and two outputs.
• Ensures high reliability with AEC-Q100 qualification suitable for demanding automotive environments.

Applications

• Automotive electronic control units requiring robust signal isolation
• Industrial communication interfaces such as CAN and LIN bus systems
• Medical equipment needing safe patient isolation barriers

Procurement Notes

Verify the specific suffix WSRWZ against official Analog Devices documentation to confirm the SOIC-16 wide body package and tube packaging format. Ensure that the AEC-Q100 qualification status aligns with your project's environmental and reliability requirements before finalizing procurement decisions.

Selection Notes

Select this component when a unidirectional four-channel isolator is required for low-power applications. The 2.7 V to 5.5 V operating range allows compatibility with various logic levels. Consider the 100 ns propagation delay and 90 Mb/s data rate limits to ensure they meet the timing constraints of your specific interface protocol.

Part Context

This part belongs to the ADUM1402 series of digital isolators. It shares the same core architecture and channel count as other variants but differs in package type and manufacturing suffix. The series is designed to replace traditional optocouplers in modern electronic designs.

Replacement Considerations

The ADUM1402CRW is a documented alternative within the same product family offering similar electrical characteristics and channel configuration.
