LM4040AIM3-8.2/NOPB

Overview

The LM4040AIM3-8.2/NOPB is a precision micropower shunt voltage reference from Texas Instruments, featuring an 8.192 V fixed reverse breakdown voltage. It operates within a wide current range of 91 μA to 15 mA and maintains a maximum temperature coefficient of 100 ppm/°C. The device provides ±0.1% initial accuracy at 25°C and functions in industrial temperatures from -40°C to +85°C. Packaged in a compact SOT-23-3 surface-mount format, it eliminates the need for external stabilizing capacitors.

Feature Summary

Capable of tolerating capacitive loads without requiring an external output capacitor
Utilizes bandgap reference curvature correction for stable performance across varying currents and temperatures
Employs fuse and Zener-zap trimming during wafer sort to ensure high initial accuracy

Applications

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

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and confirm the 'M3' designation corresponds to the SOT-23 package variant. Ensure the ordering code matches the required 8.192 V tolerance grade and temperature range specifications before procurement.

Selection Notes

Select this component when space-constrained designs require a precise shunt reference with minimal quiescent current. The A-grade tolerance ensures tight voltage accuracy, while the SOT-23 package facilitates automated assembly in dense PCB layouts.

Part Context

This part belongs to the LM4040-N family of micropower shunt references. The series offers multiple fixed voltage options and packages including SC70 and TO-92. The NOPB suffix denotes non-halogenated and lead-free construction compliant with environmental standards.
