LM4040DIM3X-6.0/NOPB

Overview

The LM4040DIM3X-6.0/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed reverse breakdown voltage of 6.0 V. It operates within an industrial temperature range of -40°C to +85°C and utilizes a SOT-23 surface-mount package. The device specifies a maximum initial accuracy tolerance of ±1% at 25°C and maintains a low temperature coefficient of 150 ppm/°C across the operating range. Designed for stability without external components, it supports a wide operating current range from a minimum of 74 μA up to a maximum of 15 mA.

Feature Summary

Eliminates the need for an external stabilizing capacitor 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
Precision audio components

Procurement Notes

Verify the specific suffix 'D' indicates the D-grade tolerance level of ±1%. Confirm the 'M3X' designation corresponds to the SOT-23 package type and tape-and-reel packaging format. Ensure the 'NOPB' suffix confirms lead-free and RoHS compliance status as per manufacturer specifications before final procurement.

Selection Notes

Select this component when a fixed 6.0 V reference is required in space-constrained designs using SOT-23 packages. It is suitable for applications needing micropower operation down to approximately 74 μA. Consider the ±1% initial accuracy and 150 ppm/°C temperature coefficient against system requirements. Verify that the industrial temperature range meets environmental needs.

Part Context

This part 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. Variants are available in SOT-23, SC70, and TO-92 packages with different tolerance grades ranging from ±0.1% to ±2%.
