• Data acquisition and measurement equipment
• Analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references

Voltage Reference Procurement Notes

Verify the specific suffix 'S5000274' against official Texas Instruments documentation, as standard datasheets typically list 'NOPB'. Confirm that this suffix denotes a valid manufacturing or packaging variant rather than a generic distributor code. Ensure compatibility with required operating temperatures and electrical specifications before integration into production designs.

Voltage Reference Selection Notes

Select this component when a precise 2.5V reference is needed in a small footprint. The ±0.2% accuracy suits applications demanding high linearity. Consider the 15 mA max current limit for load requirements. The wide temperature range makes it suitable for industrial environments. Verify if automotive qualification is required, as standard versions may differ from Q1 variants.

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 'BIM3' designation indicates a specific accuracy grade and package type. The 'X' suffix typically denotes tape-and-reel packaging. Understanding the series hierarchy helps in selecting alternative voltages or packages within the same family.

Voltage Reference FAQ

What is the typical noise performance of the LM4050BIM3X-2.5?

The datasheet specifies a peak-to-peak noise of 41 µVrms in the 0.1 Hz to 10 Hz frequency range.

Is the LM4050BIM3X-2.5 qualified for automotive applications?

Standard LM4050 parts are not automatically AEC-Q100 qualified. Automotive-grade versions exist under the LM4050-Q1 designation; verify if this specific suffix meets automotive standards.
