Voltage Reference Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability upon receipt. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain package integrity before soldering.

Voltage Reference Selection Notes

Select this component when a 5.0V reference with ±0.1% accuracy is required in a minimal footprint. Consider the SC-70-3 package constraints for PCB layout. Evaluate power dissipation limits based on maximum shunt current specifications for the target application environment.

Voltage Reference Part Context

This part belongs to the LM4050 series of precision shunt voltage references from Maxim Integrated. The series offers various fixed output voltages and accuracy grades. The 'A' suffix typically denotes tighter initial accuracy specifications compared to standard variants within the same family.

Voltage Reference Replacement Considerations

Check for pin-compatible alternatives such as the LM4040 series or other 5.0V shunt references from the same manufacturer. Verify that substitute components meet the same ±0.1% accuracy and ±15ppm/°C temperature coefficient requirements.
