LM4040AIM3-4.1+T

Overview

The LM4040AIM3-4.1+T is a precision, two-terminal shunt mode bandgap 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 0.1% and a maximum temperature coefficient of 100ppm/°C. The device operates within a wide current range from 60μA to 15mA and is guaranteed over the industrial temperature range of -40°C to +85°C. It utilizes laser-trimmed resistors for high precision and features low dynamic impedance. The component is housed in a subminiature 3-pin SOT23 surface-mount package.

Feature Summary

Ultra-small 3-pin SOT23 surface-mount package designed for space-critical applications
High precision with 0.1% maximum initial accuracy ensured by laser-trimmed resistors
Stable operation across a wide operating current range without requiring external stabilizing capacitors
Capable of tolerating any capacitive load while maintaining stable reverse breakdown voltage

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature range specifications. Confirm lead-free/RoHS compliance status indicated by the plus sign in the part number. Ensure the selected variant aligns with the intended operational environment and electrical requirements before procurement.

Selection Notes

Select this component when a highly accurate 4.096V reference is needed in a compact footprint. The 0.1% accuracy grade suits applications demanding tight tolerance. Consider the -40°C to +85°C temperature range limits during design. Evaluate power dissipation constraints if operating near maximum current limits in enclosed spaces.

Part Context

This component belongs to the LM4040 family of improved precision micropower shunt voltage references. The series offers multiple fixed reverse-breakdown voltages including 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Variants are available in different accuracy grades (0.1%, 0.2%, 0.5%, 1%) and temperature ranges (-40°C to +85°C or -40°C to +125°C).
