LM4040CIZ-8.2/NOPB

Overview

The LM4040CIZ-8.2/NOPB is a precision micropower shunt voltage reference from 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 offers a C-grade initial tolerance of ±0.5% at 25°C. The device utilizes a TO-92 package with three pins and requires a minimum operating current of 91 μA, supporting a maximum current of 15 mA.

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 accuracy across wide temperature ranges
Employs fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure high initial accuracy

Applications

Data acquisition systems
Instrumentation
Process controls
Energy management
Precision audio components

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage tolerance grade aligns with circuit requirements. Ensure the manufacturer source is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a fixed 8.192 V reference is needed in a through-hole TO-92 package. Consider the C-grade tolerance and industrial temperature limits against application demands. Evaluate the minimum operating current requirement relative to available bias currents.

Part Context

This part belongs to the LM4040-N series of precision micropower shunt voltage references. The series provides various fixed voltages including 2.048 V, 2.5 V, 3 V, 4.096 V, 5 V, 8.192 V, and 10 V.
