LT1004IPWR-2-5

Voltage Reference Overview

The LT1004IPWR-2-5 is a micropower integrated precision voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.8%. 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 a TSSOP-8 surface-mount package.

Voltage Reference Feature Summary

• Micropower integrated precision design for low power consumption
• Fixed 2.5 V output voltage with defined initial accuracy
• Shunt reference architecture supporting up to 20 mA load current

Voltage Reference Applications

• A/D and D/A converter references
• Reference for 5V systems
• Digital voltmeters

Voltage Reference Procurement Notes

Verify the specific suffix IPWR-2-5 against the manufacturer's official datasheet to confirm the TSSOP-8 package, 2.5 V output, and commercial temperature grade. Ensure compatibility with required shunt current limits and initial accuracy specifications before procurement.

Voltage Reference Selection Notes

Select this component when a stable 2.5 V reference is needed in a compact TSSOP-8 form factor. Consider the 20 ppm/°C temperature coefficient and 0.8% initial accuracy for applications requiring moderate precision without the need for laser trimming or lower temperature coefficients found in higher-tier series.

Voltage Reference Part Context

This part belongs to the LT1004 series of micropower voltage references from Texas Instruments. It serves as a direct replacement for legacy parts like the LM1004 and AS1004, offering similar functionality in modern surface-mount packaging while maintaining the core performance characteristics expected from the series.

Voltage Reference Replacement Considerations

The SPX1004S2-2.5 is documented as a direct replacement option. Verify pinout compatibility and electrical parameter alignment with the original design requirements before substitution.
