LM4040CIM3-4.1-TR

Overview

The LM4040CIM3-4.1-TR is a precision micropower shunt voltage reference manufactured by Microchip Technology, housed in a 3-pin SOT-23 surface-mount package. It provides a fixed reverse-breakdown voltage of 4.096V with an initial tolerance of ±0.5%. The device operates within a temperature range of -40°C to +85°C and features a maximum operating current of 15 mA. Key electrical characteristics include a typical temperature coefficient of 30 ppm/°C at 10 mA and a wideband noise of 80 µVrms.

Feature Summary

Bandgap reference curvature correction for stable accuracy across varying temperatures and currents
Capable of tolerating capacitive loads without requiring output capacitors
Micropower consumption suitable for battery-powered 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 the 'C' grade designation corresponds to the required ±0.5% tolerance and 100 ppm/°C temperature coefficient specifications. Ensure the manufacturer is identified as Microchip Technology, as this component lineage was previously associated with other vendors.

Selection Notes

Select this component for space-critical designs requiring a compact SOT-23 footprint. It is appropriate for applications needing a stable 4.096V reference with low quiescent current. Verify that the load current requirements fall within the 68 µA to 15 mA operating range to maintain specified performance levels.

Part Context

This part belongs to the LM4040/LM4041 family of precision micropower shunt voltage references. The LM4040 series specifically offers fixed voltage options including 2.5V, 4.096V, and 5.0V. These devices are designed to replace larger through-hole references in modern surface-mount electronics.
