Voltage Reference Procurement Notes

Verify the specific suffix and package configuration against official Texas Instruments documentation before procurement. Confirm RoHS compliance status and lead-free designation for your manufacturing requirements. Ensure the ordering part number matches the exact electrical specifications and thermal characteristics required for your design. Cross-reference datasheet revisions to confirm parameter stability.

Voltage Reference Selection Notes

Select this component when a low-cost, two-terminal shunt reference is required for applications needing 1.235 V stability. Consider the TO-92 package constraints for PCB layout. Evaluate the 20 ppm/°C temperature coefficient against system drift requirements. Verify that the 20 mA maximum shunt current meets the load regulation needs of the circuit design.

Voltage Reference Part Context

This component belongs to the LT1004 series of micropower integrated voltage references from Texas Instruments. The series includes various packages and accuracy grades. The CLP-1-2 variant specifically denotes the commercial grade temperature range and TO-92 packaging. It serves as a fundamental reference element in analog signal conditioning chains.

Voltage Reference Replacement Considerations

LT1004CPWR-1-2 is a documented alternative in the same family, offering similar electrical characteristics but in a TSSOP-8 surface-mount package. Verify pinout compatibility and thermal management differences when substituting.
