LM4040BEX3-4.1+T

Overview

The LM4040BEX3-4.1+T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 4.096V with an initial accuracy of 0.2%. The device features a maximum temperature coefficient of 100ppm/°C and operates within a temperature range of -40°C to +125°C. It utilizes a subminiature 3-pin SC70 surface-mount package (1.8mm x 1.8mm) and supports a wide operating current range from 60µA to 15mA.

Feature Summary

Ultra-small 3-pin SC70 package for space-critical applications
Laser-trimmed resistors ensure precise initial accuracy
Stable operation without external stabilizing capacitors
Capable of tolerating any capacitive load

Applications

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

Procurement Notes

Verify the specific ordering suffixes against official manufacturer documentation to confirm exact specifications such as temperature grade and packaging format. Confirm RoHS compliance status through authorized distributors or direct manufacturer channels before procurement. Ensure the selected variant matches the required thermal and electrical constraints for the target application environment.

Selection Notes

Select this component when a compact footprint is required alongside high precision in a two-terminal shunt configuration. The extended industrial temperature range (-40°C to +125°C) makes it suitable for demanding environments. Consider the 0.2% initial accuracy and low dynamic impedance for stable reference performance across varying load currents.

Part Context

This part belongs to the LM4040 family of improved precision micropower shunt voltage references. The family offers multiple fixed reverse-breakdown voltages including 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V. Variants are available in both SOT23-3 and SC70-3 packages with different accuracy grades ranging from 0.1% to 1%.
