LM4040D10IDCKR

Overview

The LM4040D10IDCKR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 10V with an initial accuracy of ±1% and a maximum temperature coefficient of 150ppm/°C. The device operates within a cathode current range from a minimum of 80μA to a maximum of 15mA. It is characterized for operation over an ambient temperature range of –40°C to 85°C. The component is housed in a 5-pin SC-70 surface-mount package.

Feature Summary

• Provides a stable 10V reference voltage with tight tolerance specifications
• Operates efficiently with low micropower consumption suitable for portable designs
• Maintains stability across wide capacitive loads without requiring external compensation components

Applications

• Data-acquisition systems
• Energy infrastructure monitoring
• Analog input modules
• Field transmitters

Procurement Notes

Verify the specific ordering suffix IDCKR to confirm the 5-pin SC-70 package configuration and industrial temperature rating. Ensure compatibility with existing PCB footprints designed for this specific package outline. Confirm that the D-grade performance meets the system requirements for temperature coefficient and initial accuracy before finalizing procurement.

Selection Notes

Select this component when a fixed 10V reference is required with moderate precision. The D-grade offers a cost-effective solution compared to higher grades while maintaining stability. Consider the SC-70 package size constraints and the need for a minimum operating current of 80μA during circuit design.
