Procurement Notes
Verify the specific suffix 'Q1' confirms automotive qualification status against the official datasheet. Ensure the operating environment aligns with the specified -40°C to +125°C temperature range. Confirm that the 2.048V output matches the system requirements before integration.
Selection Notes
Select this component when a stable, precise voltage reference is needed for automotive circuits. It is suitable for designs requiring low quiescent current and high accuracy over a wide temperature range. Consider the SOT-23-3 package size for space-constrained PCB layouts.
Part Context
This part belongs to the REF31xx family of precision voltage references from Texas Instruments. The 'Q1' designation indicates it meets automotive quality standards. It serves as a stable reference source for analog-to-digital converters and other precision analog circuits in demanding environments.
Replacement Considerations
Check for compatible parts within the same REF31xx family or other AEC-Q100 qualified voltage references with matching output voltage and accuracy specifications.
