LM4040CYM3-4.1-TR

Overview

The LM4040CYM3-4.1-TR is a precision micropower shunt voltage reference manufactured by Microchip Technology, featuring a fixed reverse-breakdown voltage of 4.096V. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 3-pin SOT-23 surface-mount package. The device maintains a maximum initial accuracy tolerance of ±0.5% at 25°C and exhibits a typical average temperature coefficient of 30 ppm/°C. Operating current ranges from a minimum of 68 µA to a maximum of 15 mA.

Feature Summary

Bandgap reference curvature correction ensures stable voltage accuracy across wide operating temperatures and currents.
Capable of tolerating capacitive loads without requiring external output capacitors for stability.
Subminiature SOT-23 package design optimizes space efficiency for critical applications.

Applications

Battery-powered equipment
Data acquisition systems
Instrumentation
Process control
Precision audio components

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm that the C-grade designation corresponds to the required ±0.5% initial accuracy and 100 ppm/°C maximum temperature coefficient specifications. Ensure the supply voltage and series resistor values accommodate the 68 µA minimum operating current requirement.

Selection Notes

Select this component for designs requiring high precision in compact form factors. Verify that the application load conditions allow operation within the specified 68 µA to 15 mA current range. Consider the low dynamic impedance and noise characteristics if signal integrity is critical in the reference circuit.

Part Context

This part belongs to the LM4040/LM4041 family of precision micropower shunt voltage references. The LM4040 variant provides fixed voltage options, while the LM4041 offers adjustable configurations. Both families share similar low-power architectures designed for industrial environments.
