Procurement Notes
Verify the specific suffix 'QPR' against official documentation to confirm the exact reel packaging configuration and tape specifications. Ensure the component grade matches the required industrial temperature range (-40 to +125 °C) for the target application. Cross-reference the datasheet revision date to confirm parameter stability. Confirm RoHS compliance status via the manufacturer's official declaration. Validate that the QFN-8 package dimensions align with the PCB footprint requirements.
Selection Notes
Select this component for applications requiring high precision voltage referencing with minimal power consumption. The low temperature coefficient ensures stability across wide thermal variations. Consider the QFN-8 package for space-constrained designs. Verify that the load capacitance requirements are met to maintain stability. Compare against other TS33 family variants if different output voltages or packages are needed.
Part Context
The TS3320AQPR belongs to the TS33 family of micropower series voltage references from STMicroelectronics. This family is designed to provide stable and precise output voltages with high initial accuracy. The components are available in various surface mount packages including QFN8, SOT23-3L, and SOT323-3L. The series is optimized for power-restricted designs while maintaining performance over an extended temperature range.
Replacement Considerations
Other members of the TS33 family, such as TS3320ACR or TS3320AMR, may serve as functional substitutes depending on the required package type (SOT23-3L vs QFN-8). Verify pinout compatibility and electrical parameters before substitution.
