Overview
The LM4040AIZ-8.2 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 TO-92 package. The device provides high accuracy with an initial tolerance of ±0.1% at 25°C and maintains stability across varying conditions through low dynamic impedance and bandgap curvature correction.
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
- Features bandgap reference temperature drift curvature correction for stable performance over wide operating temperatures
Applications
- Portable, battery-powered equipment
- Data acquisition systems
- Instrumentation
- Process controls
- Precision audio components
Procurement Notes
Verify the specific ordering suffix 'AIZ' corresponds to the TO-92 package and A-grade tolerance when sourcing. Confirm that the 8.192 V output variant matches the design requirements. Ensure compliance with the specified industrial temperature range limits for the intended application environment.
Selection Notes
Select this component for applications requiring a fixed 8.192 V reference in a through-hole TO-92 package. It is suitable where space is not critical but robust packaging is preferred. Consider the minimum operating current requirements relative to the 8.192 V version specifications compared to lower voltage variants.
