Procurement Notes

Verify the specific suffix '35' against current manufacturer documentation to confirm availability status, as this variant may be obsolete or restricted. Ensure the ordering part number matches the required tape-and-reel packaging configuration. Cross-reference the datasheet revision date to validate technical parameters before integration into designs.

Selection Notes

Select this component when automotive qualification and high channel density are required. Compare power consumption and propagation delay against standard industrial variants if operating conditions exceed automotive temperature ranges. Confirm that the 16-pin SOIC footprint aligns with the target PCB layout constraints.

Part Context

This part belongs to the ADUM1402 family of quad-channel digital isolators from Analog Devices. It shares core architectural similarities with the ADUM1400 and ADUM1401 series but offers specific channel configurations and performance characteristics tailored for complex isolation requirements in noisy environments.
