Voltage Reference Procurement Notes

Verify the specific suffix 'QBEM3' against official Texas Instruments documentation to confirm the 0.2% accuracy grade and 10 V output voltage. Ensure the component meets AEC-Q100 requirements if used in automotive designs. Cross-reference the datasheet revision date to confirm technical specifications have not changed. Confirm RoHS compliance status for environmental regulations.

Voltage Reference Selection Notes

Select this component when a stable 10 V reference is required in space-constrained automotive or industrial designs. The 0.2% accuracy suits high-precision measurement tasks. Compare against the LM4050QAIM3-10 for tighter 0.1% tolerance needs. Consider the 50 ppm/°C drift for thermal stability requirements. Evaluate the SOT-23-3 footprint compatibility during PCB layout.

Voltage Reference Part Context

This part belongs to the LM4050-N/-Q1 family of micropower shunt voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades. The 'Q' designation indicates automotive qualification. The 'B' suffix typically denotes the 0.2% accuracy bin within the series. The device serves as a compact alternative to larger package references in portable electronics.

Voltage Reference Replacement Considerations

The LM4050QAIM3-10/NOPB offers higher 0.1% accuracy. The LM4050CEM3-10/NOPB provides standard 0.5% accuracy at potentially lower cost. Verify pinout compatibility across all candidates. Check if the replacement meets the same AEC-Q100 automotive grade requirements.
