Overview
The LM4040BIM3-2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed 2.5V output. 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 surface-mount package with three pins. Key electrical parameters include a maximum shunt current of 15mA, a minimum operating current of 60µA, and a temperature coefficient of 100ppm/°C.
Feature Summary
- Provides stable fixed voltage reference in compact SOT-23 package
- High precision with ±0.2% initial accuracy for critical applications
- Micropower operation suitable for battery-powered systems
Applications
- Portable instrumentation requiring low power consumption
- Battery-operated measurement devices
- Data acquisition systems needing precise voltage references
Procurement Notes
Verify the complete part number including suffixes such as NOPB to ensure lead-free compliance and specific tolerance grades. Confirm package type matches design requirements. Check manufacturer documentation for RoHS status and automotive qualification if applicable. Ensure sourcing channels provide genuine components to avoid counterfeit risks.
Selection Notes
Select this component when high precision and low power are required in a small footprint. Compare against other LM4040 variants based on required accuracy and temperature stability. Consider thermal management and PCB layout for shunt configurations. Verify input voltage ranges exceed the reference voltage by sufficient margin for proper regulation.
Part Context
Part of the LM4040 series of micropower shunt voltage references. Designed for applications demanding precision in limited space. Offers alternatives in different voltages and accuracies within the same family. Compatible with standard surface mount assembly processes.
Replacement Considerations
LM4040BIM3-2.5/NOPB may be substituted with LM4040BIM3-2.5 if packaging or suffix differences do not impact function. Verify equivalent specifications before replacement.
