LM4040C25IDCKT

Overview

The LM4040C25IDCKT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.5%. The device operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 50 PPM/°C. It supports a maximum shunt current of 15 mA and is housed in an SC-70-5 surface-mount package.

Feature Summary

• Provides stable 2.5 V reference voltage with 0.5% initial accuracy
• Operates across extended industrial temperature range up to 125°C
• Low temperature coefficient ensures minimal drift over thermal changes

Applications

• Portable instrumentation requiring low power consumption
• Battery-powered measurement systems
• Data acquisition circuits needing precise voltage references

Procurement Notes

Verify the specific suffix IDCKT corresponds to the SC-70-5 package and cut-tape or reel packaging configuration. Confirm RoHS compliance status through official documentation. Check for end-of-life notices as availability may be limited compared to newer series replacements.

Selection Notes

Select this component when a 2.5 V reference with high precision and wide temperature stability is required. Ensure the SC-70-5 footprint matches the PCB layout. Consider the 50 PPM/°C coefficient for thermal sensitivity requirements in the target application environment.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references from Texas Instruments. It shares functional similarities with other variants like the TL4050 series but offers specific accuracy and temperature performance characteristics tailored for precision applications.

Replacement Considerations

LM4040C25IDCKRE4 is a verified equivalent variant with identical electrical specifications and packaging.
