Overview
The LM4040A30IDCKRE4 is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 3 V with an initial accuracy of 0.1%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 100 PPM/°C. It draws a typical operating supply current of 45 uA and supports a maximum shunt current of 15 mA. Packaged in an SC70-5 (SOT-353) surface-mount case, it is supplied in reel format.
Feature Summary
- Delivers high precision with 0.1% initial accuracy for stable reference applications
- Optimized for low power consumption with a 45 uA operating supply current
- Designed for compact designs using the small SC70-5 surface-mount package
Applications
- Portable battery-powered instrumentation
- Data acquisition systems requiring precise voltage references
- Microcontroller analog-to-digital converter reference inputs
- Handheld measurement devices
Procurement Notes
Verify the specific suffix IDCKRE4 against the manufacturer's latest documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and ensure the component matches the required 3 V output and 0.1% accuracy tolerance for your circuit design before procurement.
Selection Notes
Select this component when high accuracy (0.1%) is critical alongside minimal power consumption. The 45 uA quiescent current makes it suitable for battery-operated devices. Ensure the SC70-5 footprint fits the PCB layout and that the 15 mA max shunt current meets the load requirements.
Part Context
This part belongs to the LM4040 series of precision micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades (A, B, C, D). The 'A' grade denotes the highest accuracy tier within this family, providing tighter tolerances compared to standard commercial grades.
