LM4040BIM3-4.1

Overview

The LM4040BIM3-4.1 is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed reverse breakdown voltage of 4.096 V. It operates within an industrial temperature range from -40°C to +85°C and utilizes a SOT-23 surface-mount package. The device specifies an initial accuracy tolerance of ±0.2% at 25°C and maintains a maximum temperature coefficient of 150 ppm/°C across the operating range. Maximum operating current is rated at 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 performance over wide temperature ranges
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
Automotive applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific part number matches the required B-grade tolerance and industrial temperature specifications. Ensure proper handling procedures are followed due to the sensitivity of the surface-mount package.

Selection Notes

Select this component when space-critical designs require a precise shunt reference in a sub-miniature SOT-23 package. It is suitable for applications needing fixed voltage references without external stabilization components. Consider the 15 mA maximum current rating and 150 ppm/°C temperature coefficient for thermal management.

Part Context

This device belongs to the LM4040-N family of precision micropower shunt voltage references. The series offers various fixed reverse breakdown voltages including 2.048 V, 2.5 V, 3 V, 4.096 V, 5 V, 8.192 V, and 10 V. The LM4040-N is designed for easy integration into space-constrained electronic circuits requiring reliable voltage regulation.
