LM4040DIM3-4.1/NOPB

Overview

The LM4040DIM3-4.1/NOPB is a micropower shunt voltage reference from Texas Instruments, housed in a SOT-23-3 surface-mount package. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40°C to +85°C and features a maximum shunt current of 15 mA. Its low power consumption makes it suitable for battery-powered applications requiring precise voltage regulation.

Feature Summary

Provides stable precision voltage reference in compact surface-mount packaging
Designed for low-power operation with minimal quiescent current draw
Maintains specified performance across extended industrial temperature ranges

Applications

Portable instrumentation circuits
Battery-operated measurement devices
Data acquisition systems

Procurement Notes

Verify the specific suffix 'DIM3' corresponds to the desired tolerance grade and tape-and-reel packaging configuration. Confirm that the 4.096V output aligns with system requirements. Ensure compatibility with standard SOT-23 footprints during PCB layout. Check for RoHS compliance status if required by regional regulations.

Selection Notes

Select this component when a fixed 4.096V reference is needed in a small footprint. Consider the ±0.5% accuracy and 15mA current limit against load requirements. Evaluate thermal management needs within the -40°C to +85°C operating range. Compare power consumption against other shunt references for efficiency optimization.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. It shares architectural similarities with other members like the LM4040CIM3 variants but differs in specific tolerance grades and packaging options. The series is designed for general-purpose precision applications requiring stable reference voltages.
