Overview
The LM4040D20ILPE3 is a micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±1%. The device operates within a temperature range of -40°C to +85°C and features a maximum shunt current of 15 mA. It utilizes a TO-92-3 (TO-226AA) through-hole package. Key electrical characteristics include a temperature coefficient of 150 ppm/°C, a noise level of 35 µVrms from 10 Hz to 10 kHz, and a cathode current of 80 µA.
Feature Summary
- Provides stable fixed voltage reference for precision applications
- Micropower operation suitable for battery-powered systems
- Compact three-terminal through-hole packaging
Applications
- Portable instrumentation requiring precise voltage references
- Battery-operated measurement devices
- Data acquisition systems
Procurement Notes
Verify the specific suffix 'E3' indicates lead-free compliance and RoHS status as per official documentation. Confirm the package type matches the required through-hole footprint. Ensure the operating temperature range meets the application's environmental requirements. Cross-reference the datasheet for any recent design changes or qualification updates.
Selection Notes
Select this component when a low-cost, high-accuracy shunt reference is needed in a through-hole package. Consider the 150 ppm/°C temperature coefficient for thermal stability requirements. Evaluate the 80 µA cathode current against available biasing resources. Compare performance against other LM4040 variants if tighter accuracy or lower noise is required.
Part Context
This part belongs to the LM4040 series of micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The D suffix typically denotes ±1% initial accuracy. The ILPR suffix indicates a tape and reel version, while the ILP variant suggests through-hole packaging.
Replacement Considerations
LM4040D20ILP is a compatible alternative within the same series offering identical electrical specifications and through-hole packaging. Verify pinout compatibility and ensure the replacement meets all environmental and regulatory requirements.
