ADUM1201WSRZ35-RL7

Overview

The ADUM1201WSRZ35-RL7 is a dual-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 1Mbps with a maximum propagation delay of 150ns. The device provides an isolation voltage of 2500Vrms and a common-mode transient immunity of 25kV/µs. Packaged in an 8-SOIC format, it is qualified under the AEC-Q100 standard for automotive applications and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Unidirectional signal transmission using magnetic coupling technology
• Automotive-grade qualification ensuring reliability in harsh environments
• High common-mode transient immunity for noise-sensitive applications

Applications

• Automotive electronic control units requiring galvanic isolation
• Industrial communication interfaces demanding high noise immunity
• Medical equipment needing safe patient isolation barriers

Procurement Notes

Verify the specific suffix '35' against official Analog Devices documentation to confirm pinout or electrical variations compared to standard variants. Confirm current availability status as distribution channels may list this part as obsolete or limited stock. Ensure compatibility with existing PCB footprints and reflow profiles specified in the datasheet before finalizing procurement orders.

Selection Notes

Select this component when automotive certification is mandatory for digital isolation needs. Compare performance metrics such as propagation delay and power consumption against alternative isolators if system timing constraints are tight. Verify that the 8-SOIC package dimensions fit within the mechanical enclosure constraints of the target design.

Part Context

This part belongs to the ADUM1201 series of dual-channel digital isolators. It shares core architectural features with other members of the family but differs in packaging and specific qualification standards. The 'W' indicates a wide-body SOIC package, while '35' typically denotes specific manufacturing or revision details defined by the manufacturer.
