LM4030CMF-4.096/NOPB

Overview

The LM4030CMF-4.096/NOPB is an ultra-high precision shunt voltage reference manufactured by Texas Instruments, designed for surface-mount applications in a compact SOT-23 package. It delivers a fixed output voltage of 4.096 V with an initial accuracy of 0.15% and a temperature coefficient of 30 PPM/C. The device supports a maximum shunt current of 50 mA and operates reliably within a temperature range of -40°C to +125°C.

Feature Summary

• Ultra-high precision performance with tight initial accuracy tolerances
• Low temperature coefficient ensures stable voltage output across wide thermal ranges
• Compact SOT-23 surface-mount packaging facilitates space-constrained designs

Applications

• Precision analog-to-digital converter (ADC) references
• Data acquisition systems requiring high stability
• Portable instrumentation with strict power constraints

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and electrical specifications. Ensure the ordering part number matches the required voltage tolerance and package variant. Cross-reference datasheet revisions to validate manufacturing compliance and environmental certifications before final procurement decisions.

Selection Notes

Select this component when circuit requirements demand superior long-term stability and low drift compared to standard bandgap references. The 50 mA current capability allows for robust driving of downstream loads while maintaining regulation. Evaluate thermal management needs given the small footprint and high operating temperature rating.

Part Context

This part belongs to the LM4030 family of micropower shunt voltage references from Texas Instruments. The series is engineered for applications where size, precision, and power consumption are critical design parameters. It serves as a direct replacement for legacy discrete zener diode references in modern electronic systems.
