Overview
The LM4040DIM3X-6.0/NOPB is a precision micro-power shunt voltage reference manufactured by Texas Instruments, which acquired National Semiconductor. It provides a fixed output voltage of 6.0V with an initial accuracy of 1%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 150ppm/°C. It supports a maximum shunt current of 15mA and requires a minimum cathode current of 100µA for regulation. The component is housed in a compact SOT-23-3 surface-mount package.
Feature Summary
- Provides stable fixed voltage reference output
- Micro-power operation suitable for battery applications
- Compact three-terminal surface-mount packaging
Applications
- Portable instrumentation circuits
- Battery-powered measurement systems
- Data acquisition systems requiring precise analog references
Procurement Notes
Verify the manufacturer designation carefully, as the part number prefix indicates National Semiconductor, but current production is managed by Texas Instruments following their corporate acquisition. Confirm that the specific suffix corresponds to the required 6.0V output variant and ensure compatibility with the intended PCB footprint for the SOT-23-3 package during sourcing.
Selection Notes
Select this component when a fixed 6.0V reference is required in space-constrained designs. It is appropriate for applications needing low power consumption and moderate precision. Ensure the circuit design allows for sufficient current flow above the minimum operating threshold while staying within the maximum shunt current limits to maintain regulation stability.
Part Context
This device belongs to the LM4040 family of precision shunt voltage references. The family offers various fixed output voltages and accuracy grades. The 'DIM3X' suffix denotes the specific 6.0V version packaged in the small SOT-23 form factor, designed for integration into modern electronic systems where board space is limited.
Replacement Considerations
Compatible substitutes include other LM4040 variants with different voltage outputs or accuracy grades from Texas Instruments. Cross-reference with similar shunt references from other manufacturers if pin-compatible alternatives are needed, ensuring electrical parameters match the application requirements.
