LM4050AIM3-8.2/NOPB

Voltage Reference Overview

The LM4050AIM3-8.2/NOPB is a precision micropower shunt voltage reference from Texas Instruments, featuring an 8.192 V fixed reverse breakdown voltage with ±0.1% initial accuracy at 25°C. It operates within an industrial temperature range of −40°C to 85°C and supports currents from 74 μA to 15 mA. The device utilizes a compact SOT-23 package (3 mm × 1.3 mm) and requires no external stabilizing capacitor for stability with any capacitive load.

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
• Bandgap reference temperature drift curvature correction ensures stable performance across operating 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 tolerance. Confirm the package type corresponds to the design requirements. Ensure the component meets RoHS compliance standards if applicable to the manufacturing process. Cross-reference the datasheet revision to confirm electrical characteristics align with current specifications.

Voltage Reference Selection Notes

Select this component when space constraints require a sub-miniature SOT-23 package. Choose the A-grade variant for applications demanding ±0.1% initial accuracy. Verify that the operating current range accommodates the minimum 74 μA requirement and maximum 15 mA limit. Consider the extended temperature capability if ambient conditions exceed standard industrial limits.

Voltage Reference Part Context

This part belongs to the LM4050-N family of precision micropower shunt voltage references. The series offers multiple fixed voltage options including 2.048 V, 2.5 V, 4.096 V, 5 V, 8.192 V, and 10 V.
