LM4040D41ILPE3

Overview

The LM4040D41ILPE3 is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 4.096V with an initial accuracy tolerance of ±1%. The device operates within an ambient temperature range of -40°C to 85°C and features a maximum average temperature coefficient of 150ppm/°C. It requires a minimum cathode current of 45μA typical and supports a maximum continuous cathode current of 15mA. The component is housed in a TO-92-3 package.

Feature Summary

• Offers tight output tolerances and low temperature coefficients for stable performance across varying conditions.
• Designed for portable applications due to space-saving packaging and low minimum operating current requirements.
• Capable of maintaining stability with all capacitive loads without requiring external output capacitors.

Applications

• Data-Acquisition Systems
• Energy Infrastructure
• Analog Input Modules
• Field Transmitters

Procurement Notes

Verify the specific ordering suffix 'E3' against the manufacturer's latest documentation to confirm compliance status and material specifications. Ensure the selected package variant matches the required thermal and mechanical constraints for the target PCB layout. Cross-reference the exact part number with official distributor catalogs to confirm availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a fixed 4.096V reference with ±1% accuracy is required for industrial temperature environments. Consider the TO-92 package if through-hole mounting is preferred over surface-mount options. Evaluate the 150ppm/°C temperature coefficient against application sensitivity requirements compared to higher-grade alternatives like the A or B grades.

Part Context

This device belongs to the LM4040 series of precision micropower shunt voltage references from Texas Instruments. The series includes multiple voltage options and accuracy grades, utilizing fuse and Zener-zap reverse breakdown voltage trim during wafer sort to achieve specified tolerances ranging from 0.1% to 1%.
