LT1004CD-1-2

Voltage Reference Overview

The LT1004CD-1-2 is a micropower integrated precision voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 1.235 V with an initial accuracy of 0.3%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 20 ppm/°C. It supports a maximum shunt current of 20 mA and is housed in an 8-SOIC package.

Voltage Reference Feature Summary

• Micropower integrated design for low power consumption applications
• Precision fixed output voltage with high initial accuracy
• Low temperature coefficient ensuring stable performance across operating ranges

Voltage Reference Applications

• Battery-powered instrumentation systems
• Portable measurement devices requiring stable reference voltages
• Data acquisition systems needing precise voltage benchmarks

Voltage Reference Procurement Notes

Verify the specific suffix codes against official Texas Instruments documentation to ensure correct packaging and tolerance specifications. Confirm that the 8-SOIC package variant matches your PCB footprint requirements. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components, as minor suffix variations can indicate different thermal or electrical characteristics.

Voltage Reference Selection Notes

Select this component when a stable, low-power voltage reference is required for precision analog circuits. The 1.235 V output is suitable for driving ADCs or DACs where a fixed reference is preferred over adjustable types. Ensure the load current does not exceed the 20 mA maximum shunt rating to maintain regulation and prevent overheating within the specified temperature range.

Voltage Reference Part Context

This part belongs to the LT1004 series of micropower voltage references from Texas Instruments. The series includes various output voltage options and package types, such as SOT-23 and SOIC. The LT1004CD-1-2 specifically denotes the 1.235 V output version in an 8-pin SOIC package, designed for general-purpose precision applications requiring low power and high stability.

Voltage Reference Replacement Considerations

LT1004CPWR-1-2: Different package (TSSOP-8 vs SOIC). LT1004CDR-1-2: Same function but cut-tape packaging instead of tube.
