Procurement Notes
Verify the specific ordering suffix R2 against official documentation to confirm packaging details and marking codes. Ensure compatibility with the SOT-23-3 footprint and validate that the Grade B specifications meet the required accuracy thresholds for the target circuit design before finalizing procurement.
Selection Notes
Select this component when high precision and compact size are prioritized over lower cost options. The ±0.1% accuracy and 75 ppm/°C drift make it suitable for sensitive measurement circuits. Consider the minimum operating current requirements to ensure stable regulation under varying load conditions.
Part Context
This part is part of the ADR504x family of precision shunt references, which includes variants with different output voltages and accuracies. The RT suffix indicates the SOT-23-3 package type, while the B grade denotes the tighter ±0.1% initial accuracy specification compared to the standard A grade.
Replacement Considerations
The datasheet notes pin compatibility with LM4040/LM4050 devices. Verify electrical parameters such as temperature coefficient and operating current ranges match the original design requirements before substituting.
