LM4040DIM3-4.1+T

Overview

The LM4040DIM3-4.1+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 1.0%. The device features a maximum temperature coefficient of 150ppm/°C and operates within a temperature range of -40°C to +85°C. It utilizes a subminiature 3-pin SC70 surface-mount package (1.8mm x 1.8mm) and supports a shunt current capability from 60μA to 15mA.

Feature Summary

Ultra-small 3-pin SC70 package for space-critical applications
Laser-trimmed resistors ensure precise initial accuracy
Stable reverse breakdown voltage over wide operating currents
No external stabilizing capacitor required

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 grade, and compliance status. Confirm that the SC70 package variant matches the design footprint requirements. Ensure the selected part number corresponds to the intended industrial temperature range and accuracy specifications before procurement.

Selection Notes

Select this component when a compact form factor is required alongside stable voltage referencing in portable or automotive environments. The 1.0% accuracy and 150ppm/°C temperature coefficient suit general-purpose applications where extreme precision is not critical. Verify that the circuit design maintains the shunt current between 60μA and 15mA to ensure proper regulation and stability.

Part Context

This component belongs to the LM4040 family of improved precision micropower shunt voltage references. The family offers multiple fixed reverse-breakdown voltages including 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Variants are available in both SOT23 and SC70 packages with different accuracy grades ranging from 0.1% to 1.0%.
