Voltage Reference Procurement Notes

Verify the specific suffix configuration against official Texas Instruments documentation to ensure compatibility with design requirements. Confirm that the AEM3 variant matches the intended accuracy and package specifications. Cross-reference the part number with current manufacturer datasheets to validate availability and any recent product changes or lifecycle status updates before finalizing procurement plans.

Voltage Reference Selection Notes

Select this component when a stable 8.192 V reference is required in a small SOT-23-3 package. Ensure the application can accommodate the specified 15 mA maximum shunt current. Consider the 50 ppm/°C temperature coefficient for thermal stability needs. Verify that the 0.1% initial accuracy meets the system's precision requirements compared to lower-cost alternatives.

Voltage Reference Part Context

This part belongs to the LM4050 series of micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The 'A' designation typically indicates a specific accuracy bin, while 'EM3' denotes the SOT-23-3 package type. The '/NOPB' suffix signifies a lead-free, halogen-free RoHS-compliant version without specific packaging modifications affecting function.

Voltage Reference Replacement Considerations

Check for direct substitutes within the LM4050 family offering different voltage outputs or accuracies. Verify pinout compatibility if replacing with other shunt references. Consult Texas Instruments documentation for any recommended alternate part numbers due to lifecycle changes.
