Procurement Notes

Verify the specific suffix 'AMFX' against the manufacturer's official datasheet to confirm the exact tolerance grade, temperature range, and packaging configuration. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when circuit design demands high stability over wide temperature variations and tight initial accuracy. The 50 mA maximum shunt current capability allows for driving moderate loads while maintaining regulation. Consider the SOT-23-5 footprint constraints during PCB layout to ensure adequate thermal dissipation and mechanical stability for the application environment.

Part Context

This device belongs to the LM4030 series of micropower shunt voltage references. The series is designed to provide stable reference voltages in space-constrained applications. The LM4030 family offers various output voltages and accuracy grades, with the AMFX variant specifically targeting ultra-high precision requirements in industrial and medical sectors.

Replacement Considerations

Check for direct pin-compatible substitutes within the LM4030 family or other TI shunt references with matching 2.5V output and 0.05% accuracy. Verify that alternative components meet the same 30 ppm/°C temperature coefficient and 50 mA current limits to maintain circuit performance without redesign.
