LM4040AIM3X-10

Overview

The LM4040AIM3X-10 is a micropower shunt voltage reference manufactured by Texas Instruments, formerly National Semiconductor. It provides a fixed output voltage of 10 V with an initial accuracy of 0.1%. The device operates within a temperature range of -40°C to +85°C and features a maximum temperature coefficient of 150 ppm/°C. It utilizes a SOT-23-3 surface-mount package and supports a maximum shunt current of 15 mA.

Feature Summary

Provides high precision voltage referencing with 0.1% initial accuracy
Operates as a micropower shunt reference for low current applications
Maintains stability across the industrial temperature range

Applications

Portable battery-powered instrumentation
Data acquisition systems requiring stable reference voltages
Precision measurement equipment

Procurement Notes

Verify the manufacturer designation carefully, as the component was originally produced by National Semiconductor before its acquisition by Texas Instruments. Ensure the specific suffix matches the required tolerance and packaging specifications. Confirm availability status through official distributors, as older part numbers may have been superseded or discontinued in favor of updated equivalents.

Selection Notes

Select this component when a 10 V reference with tight 0.1% tolerance is required in a compact SOT-23 package. Consider the 150 ppm/°C temperature coefficient for thermal stability requirements. Verify that the operating current limits align with the power budget of the target circuit design.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The 'A' grade denotes the highest accuracy tier (0.1%), while the 'M3' indicates the SOT-23-3 package. The 'X' suffix typically denotes tape-and-reel packaging. The 'NOPB' suffix often indicates lead-free and RoHS compliance in later revisions.
