LM4040AEM3-2.5-T

Overview

The LM4040AEM3-2.5-T is a micropower shunt voltage reference manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.1%. The device operates within a temperature range of -40°C to +125°C and features a maximum temperature coefficient of 70 ppm/°C. It supports a shunt current range from 60 µA to 15 mA and is housed in an SC-70-3 (SOT-323) surface-mount package.

Feature Summary

Delivers high precision with 0.1% initial accuracy for stable reference performance.
Operates over an extended industrial temperature range up to 125°C.
Features ultra-low operating current suitable for power-constrained designs.
Maintains stability when used with capacitive loads.

Applications

Portable battery-powered instrumentation
Data acquisition systems
Microcontroller supply monitoring

Procurement Notes

Verify the specific suffix '-T' against official manufacturer documentation to confirm reel packaging requirements and tape-and-reel specifications. Ensure the component designation matches the exact 'LM4040AEM3-2.5-T' variant, as suffixes may indicate distinct manufacturing lot codes or minor packaging variations that do not alter electrical function but affect handling procedures.

Selection Notes

Select this component when a compact SC-70-3 footprint is required alongside high precision (0.1%) and wide temperature tolerance (-40°C to +125°C). It is appropriate for applications demanding low quiescent current and stability under capacitive loading conditions, distinguishing it from standard shunt references with higher noise or narrower operating ranges.

Part Context

This part belongs to the LM4040 series of improved precision micropower shunt voltage references. The series offers multiple accuracy grades (A, B, C, D) and output voltages. The 'A' grade denotes the highest accuracy tier at 0.1%, while the 'EM3' indicates the SC-70-3 surface-mount package configuration optimized for space-saving PCB layouts.
