Procurement Notes

Verify the specific suffix 'X' indicates tape and reel packaging configuration. Confirm the 'A' grade designation matches the required 0.05% accuracy and 10 ppm/°C temperature coefficient specifications. Ensure the 4.096V output voltage aligns with system requirements before procurement.

Selection Notes

Select this component when high precision and stability are critical within a compact footprint. The A-grade specification ensures tight tolerance limits suitable for demanding applications. Consider the 130 µA minimum operating current for power budget calculations and verify that the SOT-23 package meets spatial constraints.

Part Context

This part belongs to the LM4030 family of ultra-high precision shunt voltage references from Texas Instruments. The family offers options in 2.5V and 4.096V outputs across different grades (A, B, C) to balance cost and performance requirements while maintaining the small SOT-23 form factor.
