Overview
The LM4040AIM3-2.0 is a micropower shunt voltage reference from Texas Instruments, housed in a compact SOT-23-3 surface-mount package. It provides a fixed output voltage of 2.048V with an initial accuracy of ±0.1%. The device operates within a temperature range of -40°C to +85°C and features a maximum shunt current of 15mA. Its low noise characteristics and internal compensation allow for stable performance without external capacitors.
Feature Summary
- High precision output with ±0.1% initial accuracy
- Micropower operation suitable for battery-powered applications
- Internally compensated for stability without external capacitors
- Compact SOT-23-3 package for space-constrained designs
Applications
- Analog-to-digital converter (ADC) reference sources
- Digital-to-analog converter (DAC) voltage references
- Portable instrumentation requiring low power consumption
- Battery-operated measurement systems
Procurement Notes
Verify the specific suffix 'A' indicates the ±0.1% accuracy grade and 'M3' denotes the SOT-23-3 package. Confirm the '-2.0' suffix corresponds to the 2.048V output variant. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Cross-reference the datasheet revision to confirm pinout and electrical specifications match your design intent.
Selection Notes
Select this component when high accuracy and low quiescent current are critical. The ±0.1% tolerance ensures precise reference levels for sensitive analog circuits. The SOT-23-3 form factor facilitates automated assembly and reduces board space. Consider the 15mA maximum current limit for load driving capabilities and ensure thermal management aligns with the specified operating temperature range.
Part Context
Part of the LM4040 series of micropower shunt voltage references. This family offers various fixed voltage options and accuracy grades. The LM4040AIM3-2.0 specifically targets applications demanding tight tolerance and low power consumption in a small footprint.
Replacement Considerations
LM4040AIM3-2.0/NOPB is a direct equivalent with lead-free packaging. Verify compatibility with other LM4040 variants sharing the same voltage and accuracy grade.
