Overview
The LM4040BIM3X-10/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 10 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 a maximum shunt current of 15 mA and a minimum operating current of 60 µA. Its temperature coefficient is specified at 100 ppm/°C, ensuring stable performance in precision applications.
Feature Summary
- Provides a fixed 10 V reference voltage with high initial accuracy.
- Operates as a micropower shunt regulator with low minimum current consumption.
- Designed for surface-mount assembly in compact SOT-23 packages.
Applications
- Precision analog-to-digital converter (ADC) references
- Portable instrumentation circuits
- Battery-powered measurement systems
Procurement Notes
Verify the specific suffix 'NOPB' indicates lead-free composition and RoHS compliance. Confirm the 'X' designation corresponds to tape-and-reel packaging rather than cut tape. Ensure the 10V output variant matches the circuit requirements, as the LM4040 series offers multiple voltage options. Cross-reference the manufacturer part number with official TI documentation to confirm current production status and availability.
Selection Notes
Select this component when a fixed 10 V reference is required with ±0.2% initial accuracy. The 100 ppm/°C temperature coefficient suits applications needing moderate thermal stability. The SOT-23-3 package is ideal for space-constrained designs. Ensure the load current remains within the 60 µA to 15 mA operational window for proper regulation.
Part Context
This part belongs to the LM4040 family of micropower shunt voltage references. The family includes various fixed voltage outputs and accuracy grades (A, B, C, D). The LM4040 series is designed to replace traditional Zener diodes, offering superior stability and lower noise in precision reference applications.
Replacement Considerations
LM4040BIM3-10/NOPB is the non-x (cut tape) equivalent. LM4040AIM3X-10/NOPB offers improved temperature coefficient specifications. LM4040C10IDBZR provides a similar 10V shunt reference with ±0.5% accuracy.
