Overview
The LM4040B30IDCKR is a precision shunt voltage reference IC manufactured by Texas Instruments. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +85°C and features a low temperature coefficient of 100 ppm/°C. It supports a maximum cathode current of 15 mA and draws a typical operating current of 88 µA. The component is housed in a compact SC-70-5 surface-mount package, designed for applications requiring stable voltage references in space-constrained environments.
Feature Summary
- Provides a fixed 4.096 V reference output with high initial accuracy
- Operates as a shunt reference with low power consumption
- Maintains stability across industrial temperature ranges
Applications
- Portable instrumentation requiring precise voltage regulation
- Battery-powered measurement systems
- Data acquisition circuits needing stable reference sources
Procurement Notes
Verify the specific suffix IDCKR confirms the SC-70-5 package and 4.096 V output variant. Confirm RoHS compliance status and check for any recent PCN updates regarding packaging or material changes. Ensure the supplier source is authorized to guarantee authenticity and traceability for critical design implementations.
Selection Notes
Select this component when a 4.096 V reference is required in a small surface-mount footprint. Compare against other LM4040 variants based on required accuracy grades and package availability. Consider the 100 ppm/°C temperature coefficient for thermal stability requirements in the target application environment.
Part Context
This part belongs to the LM4040 family of micropower shunt voltage references from Texas Instruments. The series offers various fixed voltage options and accuracy grades in multiple packages including SOT-23 and SC-70-5. It serves as a standard solution for replacing Zener diodes in precision analog circuits.
Replacement Considerations
LM4040B41IDCKRG4 and LM4040B41IDCKRE4 are confirmed substitutes within the same family offering identical electrical characteristics and package form factor.
