LM4040AIX3-2.1+T

Overview

The LM4040AIX3-2.1+T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 2.048V with an initial accuracy of 0.1%. The device operates within a temperature range of -40°C to +85°C and features a maximum temperature coefficient of 100ppm/°C. It utilizes a subminiature 3-pin SC70 surface-mount package (1.8mm x 1.8mm) and supports a shunt current range from 60μA to 15mA.

Feature Summary

Ultra-small 3-pin SC70 package designed for space-critical applications
Laser-trimmed resistors ensure precise initial accuracy
Stable operation without requiring external stabilizing capacitors

Applications

Portable, battery-powered equipment
Notebook computers
Cell phones
Industrial process controls
Automotive systems

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type, temperature range, and accuracy grade. Confirm RoHS compliance status through authorized distributors or the manufacturer's online storefront. Ensure the selected variant matches the required operating temperature and accuracy specifications for the target application.

Selection Notes

Select this component when high precision and minimal board space are required. The 0.1% accuracy grade is suitable for demanding analog circuits. Verify that the available shunt current range meets the minimum operating requirements of the circuit design. Consider thermal derating if operating near the upper temperature limit.

Part Context

This part belongs to the LM4040 family of improved precision micropower shunt voltage references. The family offers multiple fixed reverse-breakdown voltages and various accuracy grades. The 'A' designation indicates the highest accuracy tier, while the 'IX3' suffix specifies the SC70 package and industrial temperature range.
