LM4040D25IDCKR

Overview

The LM4040D25IDCKR 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 ±1%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 150 ppm/°C. It supports a maximum cathode current of 15 mA and requires a minimum operating current of 73 µA. The component is housed in a SC-70-5 surface-mount package.

Feature Summary

Provides stable, fixed reference voltage for precision analog circuits
Micropower operation suitable for battery-powered applications
Compact SC-70-5 surface-mount packaging for space-constrained designs

Applications

Portable instrumentation requiring precise voltage references
Battery-operated measurement systems
Data acquisition systems needing stable reference sources
ADC and DAC reference inputs

Procurement Notes

Verify the specific suffix IDCKR corresponds to the SC-70-5 package and tape-and-reel configuration. Confirm the D grade indicates ±1% initial accuracy and 150 ppm/°C temperature coefficient. Ensure compatibility with existing PCB footprint and thermal requirements for the SC-70-5 form factor before procurement.

Selection Notes

Select this component when a 2.5 V reference with ±1% tolerance is required in a small surface-mount package. Consider the 150 ppm/°C temperature coefficient for thermal stability needs. Verify that the 73 µA minimum current requirement fits the circuit design constraints. Compare against higher accuracy grades if tighter tolerances are necessary.

Part Context

Part of the LM4040 family of micropower shunt voltage references from Texas Instruments. This series offers various fixed voltage options and accuracy grades in compact packages. The LM4040D25IDCKR specifically targets applications needing a 2.5 V reference with moderate precision in a small footprint.
