LM4040CIM3-4.1/NOPB

Overview

The LM4040CIM3-4.1/NOPB is a micropower shunt voltage reference from Texas Instruments, housed in a surface-mount SOT-23 package with three pins. It provides a fixed reference voltage of 4.1 V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 30 ppm/°C. It supports a maximum output current of 15 mA and has a minimum input voltage requirement of 4.1 V.

Feature Summary

Provides stable fixed voltage reference for precision applications
Micropower consumption suitable for battery-operated systems
Compact surface-mount packaging for space-constrained designs

Applications

Portable instrumentation requiring precise voltage references
Battery-powered measurement devices
Data acquisition systems needing stable analog references

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per manufacturer documentation. Confirm the 'CIM3' designation corresponds to the SOT-23 package variant. Ensure the 4.1V output matches circuit requirements before procurement. Check for any recent product change notices affecting pinout or electrical characteristics.

Selection Notes

Select this component when a 4.1V fixed reference is required with high precision. The low temperature coefficient ensures stability across varying thermal conditions. Consider the SOT-23 footprint for PCB layout compatibility. Verify that the 15mA current capability meets load demands without exceeding power dissipation limits in the application environment.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. The series offers various fixed voltage options and accuracy grades. The LM4040CIM3-4.1/NOPB specifically targets applications needing reliable performance in compact form factors. It serves as a critical reference element in analog signal chains and digital-to-analog converter circuits.
