LM4041DIM7-1.2/NOPB

Voltage Reference Overview

The LM4041DIM7-1.2/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed output of 1.225 V. It operates within an extended temperature range from -40°C to +125°C and utilizes an SC-70-5 surface-mount package. The device guarantees an initial accuracy of 1% and maintains a temperature coefficient of 150 ppm/°C. It supports a maximum shunt current of 12 mA with a minimum operating current of 60 µA. The component ensures stability across all capacitive loads without requiring external stabilizing capacitors.

Voltage Reference Feature Summary

• Provides stable operation with any capacitive load without the need for external stabilizing capacitors
• Utilizes fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure high initial accuracy
• Features bandgap reference temperature drift curvature correction for consistent performance over wide temperature ranges

Voltage Reference Applications

• Portable applications requiring space-critical sub-miniature packaging
• Battery-powered systems utilizing low quiescent current capabilities
• Data acquisition systems requiring precise voltage references
• Industrial control circuits operating in extended temperature environments

Voltage Reference Procurement Notes

Verify the specific suffix 'DIM7' corresponds to the SC-70-5 package and the '-1.2' indicates the fixed 1.225V output variant. Confirm that the 'NOPB' designation ensures compliance with RoHS standards and absence of lead-based materials. Cross-reference the manufacturer part number with official Texas Instruments documentation to validate the extended temperature rating and accuracy grade before procurement.

Voltage Reference Selection Notes

Select this component when a fixed 1.225V reference is required in a compact SC-70-5 footprint. It is suitable for designs needing extended temperature operation up to 125°C. Choose this part over adjustable variants if the circuit design does not require external resistor dividers. Ensure the application current remains within the specified 60 µA to 12 mA range for optimal regulation.

Voltage Reference Part Context

This device belongs to the LM4041-N family of precision micropower shunt voltage references. The family includes both fixed and adjustable versions available in SC-70, SOT-23, and TO-92 packages. Variants are distinguished by accuracy grades (A, B, C, D) and temperature ranges (industrial or extended). The LM4041 series is designed for applications demanding high stability and low power consumption.

Voltage Reference Replacement Considerations

Compatible substitutes include other LM4041-N variants with matching package and accuracy, such as LM4041DEM3-1.2/NOPB for SOT-23-3 packaging. Verify pinout compatibility and thermal characteristics when substituting between different package types within the same family.
