LM4040DEM3-2.5/NOPB

Overview

The LM4040DEM3-2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, offering a fixed output of 2.5 V with an initial accuracy of ±1%. Packaged in a compact SOT-23-3 surface-mount format, it operates within a temperature range of -40°C to +85°C. The device features a maximum cathode current of 15 mA and a temperature coefficient of 150 ppm/°C. It supports low-noise performance with 35 µVrms noise between 10 Hz and 10 kHz, ensuring stable reference voltages for precision analog circuits.

Feature Summary

Provides a stable 2.5 V fixed reference voltage suitable for precision applications
Operates as a shunt regulator with micropower consumption characteristics
Delivers low noise performance to maintain signal integrity in sensitive circuits

Applications

Precision data acquisition systems requiring stable voltage references
Portable instrumentation powered by battery sources
Calibration equipment needing accurate voltage standards

Procurement Notes

Verify the specific suffix 'DE' against the official datasheet to confirm the exact accuracy grade and temperature coefficient specifications. Ensure the ordering part number matches the required package type and lead-free status. Cross-reference with the manufacturer's latest documentation to confirm availability and any potential design changes or obsolescence notices before finalizing procurement.

Selection Notes

Select this component when a 2.5 V reference with ±1% initial accuracy is sufficient for the application. Consider the SOT-23-3 package for space-constrained designs. Evaluate the 150 ppm/°C temperature coefficient against thermal variations in the operating environment. Compare with higher precision variants if tighter tolerances are required for critical measurement tasks.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. The series includes various output voltages and accuracy grades, such as the LM4040AIZ and LM4040CIM3. The LM4040DEM3-2.5/NOPB specifically targets applications requiring moderate precision in a small surface-mount package, fitting within the broader portfolio of Texas Instruments' power management solutions.
