ADUM1301WSRWZ

Overview

The ADUM1301WSRWZ is a digital isolator from the Analog Devices iCoupler series, housed in a 16-lead SOIC package. It provides three unidirectional channels with magnetic coupling isolation rated at 2500 Vrms. The device supports data rates up to 90 Mb/s and operates on a single supply voltage ranging from 2.7 V to 5.5 V. Key electrical parameters include a propagation delay of 100 ns and working power currents of 29 mA and 43 mA for the respective sides. It is qualified under AEC-Q100 standards and functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for robust signal isolation without optocoupler limitations.
• Provides high common-mode transient immunity to ensure reliable data transmission in noisy environments.
• Features integrated logic and transformer windings on-chip for compact design and reduced component count.
• Supports wide operating temperature ranges suitable for demanding industrial and automotive applications.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Automotive electronics meeting AEC-Q100 qualification standards
• Power management circuits needing galvanic isolation between control and power stages
• Medical equipment requiring safe patient isolation barriers

Procurement Notes

Verify the specific suffix WSRWZ against official Analog Devices documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure that the AEC-Q100 qualification status aligns with your project's reliability requirements. Cross-reference the pinout and thermal characteristics with the latest datasheet revision to avoid integration errors during PCB layout and assembly processes.

Selection Notes

Select this component when unidirectional isolation is required for multiple signal lines within a single package. The 16-lead SOIC form factor offers a balance between channel density and board space efficiency. Consider the 2500 Vrms isolation rating and 90 Mb/s speed as primary constraints. Verify that the 2.7 V to 5.5 V supply range matches the system voltage rails and that the thermal performance meets the ambient conditions of the intended application environment.

Part Context

This part belongs to the ADUM1301 family of iCoupler digital isolators, designed to replace traditional optocouplers in various interface applications. The family leverages silicon-on-insulator (SOI) technology to integrate transformers and CMOS logic. The ADUM1301 specifically targets applications needing three-channel isolation with high-speed data transfer capabilities, offering improved reliability and smaller footprint compared to discrete optical solutions.

Replacement Considerations

ADUM1301ARWZ-RL serves as a verified substitute part number within the same product line, differing primarily in packaging format.
