Procurement Notes

Verify the specific suffix 'WSRZ' against official Analog Devices documentation to confirm the exact temperature grade and packaging configuration. Ensure compatibility with the required operating environment and check for any recent product change notices that may affect specifications or availability status.

Selection Notes

Select this component when isolated I2C connectivity is required within the specified voltage range. Consider the 400 kb/s data rate limit and 2500 Vrms isolation barrier requirements. Verify that the SOIC-8 footprint aligns with the PCB layout constraints and that the AEC-Q100 qualification meets the target application's reliability standards.

Part Context

This part belongs to the ADUM1250 series of digital isolators designed for high-speed, low-power isolation applications. The series leverages silicon dioxide (SiO2) based transformer technology to provide robust electrical isolation between circuit domains while maintaining signal integrity across the isolation barrier.
