Overview
The LM4041CIDCKR is a micropower shunt voltage reference manufactured by Texas Instruments. It provides a stable 1.233 V output with an initial accuracy of ±0.2% at 25 °C and a maximum temperature coefficient of 100 ppm/°C. The device operates within a current range of 80 µA to 12 mA and maintains stability across all capacitive loads without requiring external stabilization capacitors. It is housed in a compact SC-70-5 surface-mount package, suitable for space-constrained designs.
Feature Summary
- Provides high precision with ±0.2% initial accuracy and low temperature drift
- Operates stably with any capacitive load without external components
- Features ultra-low operating current for power-efficient applications
Applications
- Data acquisition systems
- Portable battery-powered equipment
- Precision audio circuits
- Process control instrumentation
Procurement Notes
Verify the specific suffix 'CKR' indicates the SC-70-5 package and tape-and-reel delivery format. Confirm the 'I' grade designation corresponds to the industrial temperature range (-40°C to +85°C). Ensure the order matches the required ±0.2% tolerance specification for your circuit design.
Selection Notes
Select this component when a fixed or adjustable reference near 1.2V is needed in a small footprint. It is ideal for designs prioritizing low quiescent current and high stability under varying capacitive loads. Consider the SC-70-5 package dimensions for board layout constraints.
Part Context
This part belongs to the LM4041-N family of precision micropower shunt references. The series offers various accuracy grades and packages, including SOT-23 and TO-92. The LM4041CIDCKR specifically utilizes the SC-70-5 form factor for dense PCB layouts while maintaining the family's core performance characteristics.
Replacement Considerations
LM4041BIDCKR (±0.2% accuracy) and LM4041DIDCKR (±1% accuracy) are direct pin-compatible alternatives within the same package. For higher accuracy requirements, consider the A-grade variant if available in the SC-70-5 package.
