Overview
The LM4040AIZ-2.0/NOPB is a precision shunt voltage reference from Texas Instruments, offering a nominal output of 2.048 V with an initial accuracy of ±0.1%. Housed in a TO-92 three-pin through-hole package, it operates within a temperature range of -40°C to +85°C. The device features a maximum cathode current of 15 mA and a minimum operating current of 75 µA. It exhibits a temperature coefficient of 150 ppm/°C and complies with RoHS standards.
Feature Summary
- Provides high-precision fixed voltage reference with ±0.1% initial accuracy
- Operates as a two-terminal shunt reference for stable regulation
- Supports through-hole mounting in standard TO-92 packages
Applications
- Precision analog-to-digital converter (ADC) reference sources
- Calibration circuits requiring stable voltage benchmarks
- Portable instrumentation power management systems
Procurement Notes
Verify the specific suffix 'AIZ' corresponds to the desired accuracy grade and package variant against the official datasheet. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance. Ensure the procurement channel provides valid traceability documentation for the Texas Instruments manufacturer part number to guarantee component authenticity and quality assurance.
Selection Notes
Select this component when a fixed 2.048 V reference with tight initial tolerance is required in a through-hole design. Compare the 150 ppm/°C temperature coefficient against application thermal stability needs. Evaluate the 15 mA maximum current limit against load requirements. Consider alternative packages if surface-mount space constraints exist.
Part Context
This part belongs to the LM4040 series of micropower shunt voltage references designed for general-purpose precision applications. The series offers various fixed voltage options and accuracy grades. The LM4040AIZ-2.0/NOPB specifically targets applications needing reliable performance in compact through-hole layouts while maintaining low power consumption characteristics typical of the family.
Replacement Considerations
Direct substitutes include LM4040AIM3-2.0/NOPB and LM4040AIM3X-2.0/NOPB, which offer similar electrical specifications but utilize SOT-23 surface-mount packaging instead of TO-92.
