LM4040EEM3X-2.5/NOPB

Overview

The LM4040EEM3X-2.5/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, delivering a nominal output of 2.5 V. It operates within an extended temperature range from -40 °C to +125 °C and features a maximum initial accuracy of 1%. The device supports a maximum shunt current of 15 mA and utilizes a SOT-23-3 surface-mount package.

Feature Summary

Provides stable precision voltage reference in a compact surface-mount form factor
Operates reliably across an extended industrial temperature range up to 125 °C
Designed for low power consumption suitable for battery-powered applications

Applications

Portable instrumentation requiring precise voltage standards
Battery-operated measurement systems
Data acquisition circuits needing stable reference sources

Procurement Notes

Verify the specific suffix 'EEM3X' against official Texas Instruments documentation to confirm package type and tape-and-reel configuration. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the exact part number with the manufacturer's current datasheet to validate availability and any recent design changes or obsolescence notices before finalizing procurement.

Selection Notes

Select this component when a 2.5 V reference is required in a SOT-23-3 package with operation up to 125 °C. Compare the 1% initial accuracy and 150 ppm/°C temperature coefficient against system tolerance requirements. Consider the micropower characteristics if minimizing quiescent current in battery-driven designs is critical for the application.

Part Context

This device belongs to the LM4040-N/LM4040Q-N family of precision micropower shunt voltage references. The family offers various fixed output voltages and accuracy grades. The 'EEM3X' designation indicates a specific SOT-23 variant optimized for high-volume surface-mount assembly processes within the broader Texas Instruments voltage reference portfolio.
