LM4040BIM3-2.0/NOPB

Overview

The LM4040BIM3-2.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 2.048 V. It features an initial accuracy of 0.2% and operates within a temperature range of -40°C to +85°C. The device utilizes a SOT-23-3 surface-mount package with three pins. Key electrical specifications include a maximum shunt current of 15 mA, a minimum operating current of 60 µA, and a temperature coefficient of 150 ppm/°C.

Feature Summary

Micropower operation with low quiescent current consumption suitable for battery-powered systems
High precision fixed voltage output with tight initial accuracy tolerance
Compact SOT-23-3 surface-mount package design for space-constrained applications

Applications

Portable instrumentation requiring stable reference voltages
Battery-operated measurement devices
Data acquisition systems needing precise analog references

Procurement Notes

Verify the specific suffix (e.g., NOPB) matches the required lead-free and RoHS compliance standards. Confirm the package type is SOT-23-3 and the output voltage is exactly 2.048 V. Ensure the temperature grade corresponds to industrial requirements (-40°C to +85°C). Cross-reference the manufacturer part number with official TI documentation to avoid counterfeit components.

Selection Notes

Select this component when a fixed 2.048 V reference is required in a small footprint. It is suitable for applications demanding 0.2% accuracy and low power consumption. Consider the 15 mA max shunt current limit for load regulation needs. Compare against other LM4040 variants if different voltage outputs or accuracy grades are needed.

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 'B' indicates 0.2% accuracy, 'I' denotes industrial temperature range, and 'M3' specifies the SOT-23-3 package. The 'NOPB' suffix confirms it is a lead-free product without green material restrictions.
