LM4040BIM3X-10

Overview

The LM4040BIM3X-10 is a precision micropower shunt voltage reference from Texas Instruments, providing a fixed reverse breakdown voltage of 10 V. It operates within an industrial temperature range of -40°C to +85°C and features a maximum initial accuracy of ±0.2% at 25°C. The device requires a minimum operating current of 100 μA and supports a maximum operating current of 15 mA. It utilizes a SOT-23 surface-mount package with three pins.

Feature Summary

• Eliminates the need for external stabilizing capacitors 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 across wide temperature ranges

Applications

• Data acquisition systems
• Instrumentation
• Process controls
• Energy management
• Automotives

Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging configuration. Confirm that the 'B' grade designation corresponds to the required ±0.2% tolerance specification for your design. Ensure the sourcing channel provides original manufacturer documentation to validate the component's authenticity and traceability before integration into production.

Selection Notes

Select this component when a fixed 10 V reference is required in a compact SOT-23 footprint. The B-grade tolerance suits applications needing tighter accuracy than standard grades but without the premium cost of A-grade parts. Verify that the circuit can supply the minimum 100 μA operating current required for proper regulation.

Part Context

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