LM4040BIM3X-8.2

Overview

The LM4040BIM3X-8.2 is a precision micropower shunt voltage reference from Texas Instruments, providing a fixed reverse breakdown voltage of 8.192 V. It operates within an industrial temperature range of -40°C to +85°C and features B-grade initial tolerance. The device utilizes a SOT-23 surface-mount package with three pins. Key electrical characteristics include a maximum temperature coefficient of 100 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
Uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure high accuracy
Bandgap reference temperature drift curvature correction ensures stable voltage over wide temperature ranges

Applications

Portable, battery-powered equipment
Data acquisition systems
Instrumentation
Process controls
Automotive applications

Procurement Notes

Verify the specific grade suffix (e.g., 'B' for ±0.2% tolerance) against design requirements. Confirm the package type matches the PCB footprint. Ensure the operating current stays within the specified minimum and maximum limits for the 8.192 V variant. Check for automotive qualification if required by the application environment.

Selection Notes

Select this component when a precise 8.192 V reference is needed in a space-constrained design. The SOT-23 package offers a small form factor suitable for portable devices. Consider the B-grade tolerance and temperature coefficient for applications requiring moderate precision without the cost of higher grades.

Part Context

This part belongs to the LM4040-N family of precision micropower shunt voltage references. The family includes various fixed voltages such as 2.048 V, 2.5 V, 3 V, 4.096 V, 5 V, and 10 V. The LM4040-N series is designed for applications requiring low power consumption and high stability in compact packages like SOT-23, SC70, and TO-92.
