LM4050QAEM3X2.0/NOPB

Voltage Reference Overview

The LM4050QAEM3X2.0/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, operating within an automotive-grade temperature range of -40°C to +125°C. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±0.5% and a temperature coefficient of 50 ppm/°C. The device supports a maximum shunt current of 15 mA and features a low cathode current of 80 µA. Packaged in a compact SOT-23-3 surface-mount format, it meets AEC-Q100 qualification standards for automotive applications.

Voltage Reference Feature Summary

Automotive-grade reliability certified under the AEC-Q100 standard for robust performance in vehicle environments.
Micropower architecture designed to minimize quiescent current consumption during operation.
Precision voltage regulation maintained across wide industrial and automotive temperature extremes.

Voltage Reference Applications

Automotive electronic systems requiring stable reference voltages
Data acquisition circuits needing high-precision analog references
Portable battery-powered instrumentation

Voltage Reference Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeiting risks. Confirm specific ordering suffixes match exact tolerance and packaging requirements. Check for recent Product Change Notifications or discontinuance notices from Texas Instruments to ensure long-term supply availability for production cycles.

Voltage Reference Selection Notes

Select this component when automotive qualification is mandatory alongside precise 2.048 V referencing. Compare against non-automotive variants if environmental ruggedness is not required. Ensure input voltage exceeds the reference output plus necessary headroom for proper shunt regulation within the specified current limits.

Voltage Reference Part Context

This part belongs to the LM4050-N/-Q1 family of precision micropower shunt voltage references. It shares functional similarities with other members like the LM4050CEM3 series but distinguishes itself through automotive certification and specific output voltage options tailored for high-accuracy measurement applications.
