Procurement Notes

Verify the specific suffix 'AMR' against the official STMicroelectronics datasheet to confirm package type and tape/reel specifications. Ensure the ordering code matches the required quantity per reel. Confirm RoHS compliance status through the manufacturer's documentation before procurement.

Selection Notes

Select this component when a stable 2.5 V reference is required with low quiescent current. The QFN-8 package suits space-constrained designs. Verify that the 0.15% initial accuracy and 30 PPM/C temperature coefficient meet the system's error budget requirements.

Part Context

This part belongs to the TS33 series of micropower voltage references from STMicroelectronics. The series includes various output voltages and packages. The TS3325 variant specifically targets applications needing a precise 2.5 V reference with minimal power draw.

Replacement Considerations

Check for direct pin-compatible substitutes within the TS33 family or other manufacturers' micropower references. Verify electrical parameters such as output voltage, accuracy, and temperature coefficient match the original design requirements.
