LM4040DIM3X-8.2/NOPB

Overview

The LM4040DIM3X-8.2/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring an 8.192 V nominal output. It operates within the industrial temperature range of -40°C to +85°C and utilizes a SOT-23 surface-mount package. The device provides a D-grade initial accuracy of ±1% at 25°C with a maximum temperature coefficient of 150 ppm/°C. It requires a minimum operating current of 91 μA and supports a maximum reverse current of 15 mA.

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 across wide temperature ranges

Applications

• Data acquisition systems
• Portable battery-powered equipment
• Precision audio components
