LM4050AEM3-8.2

Voltage Reference Overview

The LM4050AEM3-8.2/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring an 8.192 V fixed reverse breakdown voltage with ±0.1% initial accuracy at 25°C. It operates within an extended temperature range of -40°C to +125°C and utilizes a compact SOT-23 surface-mount package measuring 3 mm × 1.3 mm. The device requires no external stabilizing capacitor for stability with any capacitive load, supports a maximum operating current of 15 mA, and exhibits a typical wideband noise of 150 μVrms across the 10 Hz to 10 kHz frequency band.

Voltage Reference Feature Summary

• Eliminates the need for external stabilizing capacitors while ensuring stability with any capacitive load
• Utilizes fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure high accuracy
• Incorporates bandgap reference temperature drift curvature correction for stable performance over varying temperatures

Voltage Reference Applications

• Portable, battery-powered equipment
• Data acquisition systems
• Instrumentation
• Process control
• Precision audio components

Voltage Reference Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and packaging format. Confirm the component is the standard industrial or extended version rather than the automotive LM4050-N-Q1 variant unless explicitly specified. Ensure the datasheet revision aligns with the manufacturing lot requirements for your design.

Voltage Reference Selection Notes

Select this component when space constraints require a sub-miniature SOT-23 package alongside high precision. The A-grade tolerance ensures tight initial accuracy suitable for critical measurement circuits. Verify that the minimum operating current requirement fits within the available bias current budget of the application circuit.

Voltage Reference Part Context

This part belongs to the LM4050-N family of precision micropower shunt voltage references from Texas Instruments. The family offers multiple fixed voltage options ranging from 2.048 V to 10 V in the same small footprint. The 'A' designation indicates the highest initial accuracy grade, while 'E' specifies the extended temperature range capability.
