Voltage Reference Procurement Notes

Verify the specific /V suffix against official documentation to confirm automotive qualification status, as this ordering suffix indicates AEC-Q100 compliance. Confirm that the SC70 package code matches the required footprint dimensions. Ensure the component source is traced directly to Analog Devices or authorized distributors to guarantee authenticity and proper handling of the micropower shunt reference.

Voltage Reference Selection Notes

Select this part when space constraints necessitate the SC70 package over the SOT23 variant while maintaining high precision. The 0.2% initial accuracy grade (B) offers a balance between cost and performance. Verify that the application circuit maintains the shunt current between 60µA and 15mA to ensure stable operation across the full industrial temperature range without requiring external compensation components.
