LM4040DIZ-8.2/NOPB

Overview

The LM4040DIZ-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 provides an initial accuracy tolerance of ±1%. The device utilizes a SOT-23 surface-mount package with three pins. Electrical characteristics include a maximum temperature coefficient of 150 ppm/°C and a wide operating current range from 91 μA to 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 and low dynamic impedance for stable performance
Employs fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure high accuracy

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required tolerance grade and temperature rating. Confirm the package type corresponds to the design layout. Ensure the NOPB designation aligns with environmental compliance requirements. Cross-reference the manufacturer part number against official datasheets to validate electrical specifications before integration.

Selection Notes

Select this component when a fixed 8.192 V reference is required in a compact SOT-23 footprint. Consider the ±1% initial accuracy and 150 ppm/°C temperature coefficient for circuit precision needs. Evaluate the minimum operating current of 91 μA against system power constraints. Verify compatibility with the intended industrial temperature range of -40°C to +85°C.

Part Context

This device belongs to the LM4040-N family of precision micropower shunt voltage references. The family offers various fixed voltages including 2.048 V, 2.5 V, 3 V, 4.096 V, 5 V, 8.192 V, and 10 V. Available packages include SOT-23, TO-92, and SC70. The series is designed for space-critical applications requiring high stability without external compensation components.
