LM4040EIM3-2.5/NOPB

Overview

The LM4040EIM3-2.5/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed output of 2.5 V with an initial accuracy of ±0.5%. It operates within a temperature range of -40 °C to +85 °C and exhibits a temperature coefficient of 100 ppm/°C. The device supports a maximum cathode current of 15 mA and maintains low noise performance at 35 µVrms. Packaged in a compact SOT-23-3 surface-mount format, it is designed for applications requiring stable voltage references with minimal power consumption.

Feature Summary

Provides a stable 2.5 V reference voltage with high precision and low temperature drift
Operates efficiently with micropower consumption suitable for battery-powered systems
Features low noise characteristics to ensure signal integrity in sensitive circuits

Applications

Portable instrumentation requiring precise voltage references
Battery-operated measurement devices
Data acquisition systems needing stable analog references

Procurement Notes

Verify the specific suffix EIM3 against the official Texas Instruments datasheet to confirm package type and temperature grade. Ensure the NOPB designation aligns with lead-free compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the 2.5 V output variant matches your circuit design specifications before procurement.

Selection Notes

Select this component when a fixed 2.5 V reference with ±0.5% initial accuracy is required. It is suitable for designs prioritizing low power consumption and moderate precision over automotive-grade reliability. Consider alternative packages if through-hole mounting is necessary, as this model is strictly surface-mount. Evaluate thermal management needs based on the specified operating temperature range.

Part Context

This device belongs to the LM4040-N series of precision micropower shunt voltage references from Texas Instruments. The series offers various output voltages and accuracy grades to support diverse electronic design needs. The LM4040EIM3-2.5/NOPB specifically targets general-purpose applications requiring reliable voltage referencing in a small footprint.
