LM4050QCEM3-2.0/NOPB

Voltage Reference Overview

The LM4050QCEM3-2.0/NOPB is an automotive-grade micropower shunt voltage reference manufactured by Texas Instruments, derived from the National Semiconductor portfolio. It provides a fixed output of 2.0V with high precision. Key electrical parameters include an initial accuracy of 0.1%, a temperature coefficient of 50ppm/°C, and a maximum shunt current of 15mA. The device operates within a temperature range of -40°C to +125°C and meets AEC-Q100 qualification standards for automotive applications.

Voltage Reference Feature Summary

Automotive-grade reliability compliant with AEC-Q100 standards
High precision micropower shunt voltage reference design
Low temperature coefficient ensuring stable performance across wide thermal ranges

Voltage Reference Applications

Automotive electronic control units requiring precise voltage references
Data acquisition systems in harsh environments
Portable instrumentation with strict power constraints

Voltage Reference Procurement Notes

Verify the manufacturer origin as Texas Instruments, which acquired National Semiconductor. Confirm the specific suffix 'QCEM3' indicates the Q100 grade and SOT-23 package. Ensure the 'NOPB' designation confirms lead-free status. Cross-reference the 2.0V output option against the datasheet to confirm availability of this specific voltage variant.

Voltage Reference Selection Notes

Select this component when automotive qualification (AEC-Q100) is mandatory alongside high precision (0.1%). The 2.0V output is suitable for low-voltage ADC references. Consider the 50ppm/°C temperature coefficient for applications requiring stability over the full industrial automotive temperature range (-40°C to +125°C).

Voltage Reference Part Context

This part belongs to the LM4050 family of micropower shunt voltage references. While originally developed by National Semiconductor, production and support are now managed by Texas Instruments following their acquisition. The 'Q' prefix denotes automotive qualification, distinguishing it from standard commercial variants.
