LM4040D10ILPR

Overview

The LM4040D10ILPR is a micropower shunt voltage reference manufactured by Texas Instruments, providing a fixed output of 10V. It features an initial accuracy of ±1% and a temperature coefficient of 150ppm/°C. The device operates within a temperature range of -40°C to +85°C and supports a maximum shunt current of 15mA with a minimum operating current of 100µA. Packaged in a TO-92-3 through-hole format, it exhibits low noise characteristics suitable for precision applications.

Feature Summary

• Micropower operation with low quiescent current consumption
• High precision fixed voltage output with tight initial accuracy tolerance
• Low noise performance for sensitive analog circuits
• Robust thermal stability across industrial temperature ranges

Applications

• Portable instrumentation requiring stable reference voltages
• Battery-powered measurement systems
• Data acquisition systems
• Microcontroller supply monitoring

Procurement Notes

Verify the specific suffix ILPR indicates the TO-92-3 through-hole package variant distinct from surface-mount options. Confirm the D grade corresponds to the ±1% accuracy specification. Ensure the ordering part number matches the required lead time and packaging format such as reel or cut tape directly from authorized distributors.

Selection Notes

Select this component when a 10V reference is required in a through-hole configuration. Compare against other LM4040 variants based on necessary accuracy grades and package types. Consider the 150ppm/°C temperature coefficient for thermal drift requirements in the target application environment.

Part Context

This device belongs to the LM4040 family of micropower shunt voltage references. The family offers various fixed output voltages and accuracy grades. The LM4040 series is designed for applications where space and power consumption are critical constraints while maintaining high precision.

Replacement Considerations

Check for direct pin-compatible substitutes within the LM4040 series offering different accuracies or packages. Verify equivalent specifications from other manufacturers if sourcing alternatives.
