LM4040BIM3-8.2

Overview

The LM4040BIM3-8.2 is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring an 8.192 V nominal output. It operates within a reverse current range of 91 μA to 15 mA and maintains a maximum temperature coefficient of 100 ppm/°C in the industrial grade. The device utilizes a SOT-23 surface-mount package and provides high accuracy with initial tolerances of ±0.2% at 25°C.

Feature Summary

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

Applications

• Portable, battery-powered equipment
• Data acquisition systems
• Instrumentation
• Process controls
• Automotive applications

Procurement Notes

Verify the specific suffix against official documentation to confirm tolerance grades and temperature ranges. Confirm package availability and lead times directly with authorized distributors or the manufacturer. Ensure compliance with RoHS directives and check for automotive qualification requirements if applicable to the design.

Selection Notes

Select this component when a fixed 8.192 V reference is required in a compact SOT-23 footprint. Consider the B-grade tolerance specifications and the 100 ppm/°C temperature coefficient for industrial environments. Evaluate the minimum operating current requirement of 91 μA against system power constraints.
