LM4040DIMX-10.0

Overview

The LM4040DIMX-10.0 is a precision 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 1% and a maximum temperature coefficient of 150 ppm/°C. The device operates within a temperature range of -40 °C to +85 °C and supports a maximum shunt current of 15 mA. It is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Provides stable 10 V reference output suitable for industrial environments
• Designed for space-constrained applications via compact SOT-23-3 packaging
• Operates with low quiescent current for power-efficient designs

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement systems
• Data acquisition circuits

Procurement Notes

Verify the manufacturer designation carefully, as this component was originally produced by National Semiconductor before its acquisition by Texas Instruments. Ensure the ordering suffix matches the required tolerance and temperature grade specifications for your specific design requirements.

Selection Notes

Select this component when a 10 V reference with 1% initial accuracy is required. Consider the 150 ppm/°C temperature coefficient for thermal stability needs. Verify that the SOT-23-3 footprint aligns with the PCB layout constraints and that the 15 mA maximum current capability meets the load requirements.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The 'DI' suffix typically denotes the 1% accuracy grade and industrial temperature range (-40°C to +85°C). The 'M3X' indicates the SOT-23-3 surface-mount package variant.

Replacement Considerations

LM4040DIM3-10.0/NOPB is a confirmed equivalent part number from Texas Instruments offering identical electrical characteristics and pinout compatibility.
