Overview
The LM4040C10ILPR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 10V with an initial accuracy tolerance of ±0.5%. The device features a maximum temperature coefficient of 100ppm/°C and operates within an ambient temperature range of -40°C to 85°C. It requires a minimum cathode current of 45μA typical and supports a maximum continuous cathode current of 15mA. The component is housed in a TO-92-3 package.
Feature Summary
- Offers low dynamic impedance and low noise for stable performance across wide operating currents and temperatures
- Requires no external capacitors for operation and remains stable with all capacitive loads
- Utilizes fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure tight output tolerances
Applications
- Data-Acquisition Systems
- Energy Infrastructure
- Analog Input Module
- Field Transmitters
- Precision Audio
Procurement Notes
Verify the specific ordering suffix 'LP' corresponds to the TO-92 package configuration required for your design, as the LM4040 series utilizes different suffixes for SOT-23 and SC-70 packages. Confirm that the C-grade specifications meet the system's accuracy requirements before finalizing procurement.
Selection Notes
Select this component when a 10V reference is needed with industrial temperature stability. Ensure the circuit design maintains the cathode current between the minimum requirement and the 15mA maximum limit. Consider the TO-92 package dimensions if space constraints are a factor compared to surface-mount alternatives.
Part Context
