LT1004ID-2-5

Voltage Reference Overview

The LT1004ID-2.5 is a micropower integrated voltage reference manufactured by Texas Instruments, belonging to the LT1004 series. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.8% and a temperature coefficient of 20 ppm/°C. The device operates within a junction temperature range of -40°C to +85°C and supports a maximum shunt current of 20 mA. It is housed in an SOIC-8 surface-mount package.

Voltage Reference Feature Summary

• Micropower integrated design for low energy consumption
• Fixed 2.5 V precision output voltage
• Shunt reference topology suitable for compact circuits

Voltage Reference Applications

• Portable battery-powered instrumentation
• Data acquisition systems requiring stable references
• Precision analog-to-digital converter biasing

Voltage Reference Procurement Notes

Verify the specific suffix ID-2.5 against the official Texas Instruments datasheet to confirm the SOIC-8 package and industrial temperature grade. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement.

Voltage Reference Selection Notes

Select this component when a fixed 2.5 V reference with 0.8% initial accuracy is required. Consider the 20 ppm/°C temperature coefficient for thermal stability needs. Verify that the 20 mA maximum shunt current meets the circuit load requirements.

Voltage Reference Part Context

Part of the LT1004 family of micropower voltage references from Texas Instruments. This series includes variants with different output voltages and accuracies, designed for applications demanding low power consumption and stable performance in space-constrained environments.

Voltage Reference Replacement Considerations

LT1004CDR-2.5: Same series, different package (SOIC-8 vs potentially similar). REF1004I-2.5: Higher accuracy (0.4%) but larger package (SOIC-8). LM285-2.5: Zener-based alternative with lower accuracy.
