Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to ensure correct packaging and variant selection. Confirm availability status as supply constraints may apply. Cross-reference the datasheet revision history for any recent product change notifications that might affect pinout or electrical characteristics prior to final procurement decisions.

Selection Notes

Select this component when a single-channel, low-power isoSPI interface is required for broad market applications. Consider the 32-QFN package dimensions for PCB layout compatibility. Ensure the design accommodates the specified voltage range and temperature extremes. Evaluate the need for bidirectional communication versus unidirectional alternatives if channel count requirements differ.
