LM4040CIM3X-2.0/NOPB

Overview

The LM4040CIM3X-2.0/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, which acquired National Semiconductor. It provides a nominal output voltage of 2.048 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 and a minimum operating current of 60 µA. It is housed in a SOT-23-3 surface-mount package.

Feature Summary

Provides stable precision voltage reference output
Designed for low power consumption applications
Utilizes compact three-terminal surface-mount packaging

Applications

Portable battery-powered instrumentation
Data acquisition systems
Handheld meters

Procurement Notes

Verify the manufacturer designation as Texas Instruments due to the corporate acquisition history. Confirm the specific suffix 'NOPB' indicates lead-free and RoHS compliance status. Ensure the ordering part number matches the required tolerance and temperature grade specifications for the intended circuit design.

Selection Notes

Select this component when a precise 2.048 V reference is required in space-constrained designs. The SOT-23-3 package facilitates automated surface-mount assembly. Consider the 60 µA minimum current requirement to ensure proper regulation during operation.

Part Context

This component belongs to the LM4040 series of micropower shunt voltage references. The series offers various fixed voltage options and accuracy grades. The CIM3X variant specifically denotes the industrial temperature range and SOT-23-3 package configuration.
