LM4040CIM3X-8.2/NOPB

Overview

The LM4040CIM3X-8.2/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed reverse breakdown voltage of 8.192 V. It operates within an industrial temperature range of -40°C to +85°C and utilizes a SOT-23 surface-mount package. The device requires a minimum operating current of 91 μA and supports a maximum operating current of 15 mA. It exhibits a maximum temperature coefficient of 100 ppm/°C and maintains a typical wideband noise of 35 μVrms across the 10 Hz to 10 kHz frequency band.

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

Applications

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