Overview
The LM4040AIM3-2.0/NOPB is a precision micropower shunt voltage reference from Texas Instruments, offering a nominal output voltage of 2.0V with an initial accuracy of ±0.5%. It operates within a temperature range of -40°C to +85°C and features low dynamic impedance of 1.6 ohms typical at 1mA. The device draws a quiescent current of 100µA maximum and supports a load current range from 175µA to 15mA. Packaged in the SOT-23-3 surface-mount case, it provides stable reference performance for space-constrained designs requiring high precision.
Feature Summary
- Provides precise 2.0V reference voltage with tight initial tolerance
- Operates efficiently with minimal power consumption suitable for battery applications
- Maintains stability across wide industrial temperature ranges
Applications
- Portable instrumentation requiring low power supply references
- Data acquisition systems needing accurate analog-to-digital conversion references
- Battery-powered equipment utilizing series regulator topologies
Procurement Notes
Verify the complete part number including suffixes such as NOPB which indicates lead-free status and RoHS compliance. Confirm package type matches design requirements. Ensure ordering documentation specifies the correct temperature grade and accuracy class. Cross-reference manufacturer datasheets for latest revision updates before final procurement decisions.
Selection Notes
Select this component when a fixed 2.0V reference is required with high precision and low power consumption. Consider the SOT-23 package for compact PCB layouts. Evaluate thermal management needs based on operating temperature range. Compare dynamic impedance specifications against circuit sensitivity requirements to ensure adequate noise rejection.
Part Context
This device belongs to the LM4040 family of micropower shunt voltage references designed for general-purpose applications. It complements other precision reference solutions by offering a balance of accuracy, size, and power efficiency. The family includes various voltage options and accuracy grades to suit diverse electronic design needs.
Replacement Considerations
Direct substitutes include LM4040AIM3-2.0E/NOPB or LM4040BIM3-2.0/NOPB depending on required accuracy grade. Verify pinout compatibility and thermal characteristics when replacing. Ensure replacement parts meet same regulatory compliance standards.
