LT1004IPWR-2-5

Voltage Reference Overview

The LT1004IPWR-2.5 is a micropower integrated precision voltage reference manufactured by Texas Instruments, formerly National Semiconductor. It provides a stable 2.5 V output 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. Packaged in a TSSOP-8 surface-mount format, it is available in cut tape, reel, and MouserReel configurations.

Voltage Reference Feature Summary

• Micropower integrated precision design for low power consumption
• Shunt reference architecture ensuring stable voltage regulation
• Surface-mount TSSOP-8 package for compact circuit integration

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage standards
• Battery-powered instrumentation requiring stable bias voltages
• Portable measurement equipment calibration circuits

Voltage Reference Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor, when sourcing this component. Confirm the specific suffix indicates the 2.5V output variant and TSSOP-8 packaging. Ensure the order matches the required initial accuracy and temperature coefficient specifications for your application's precision requirements.

Voltage Reference Selection Notes

Select this component when a low-cost, micropower shunt reference is needed for applications requiring moderate precision. The 2.5V output is suitable for driving ADCs and DACs directly. Consider the 0.8% initial accuracy and 20 ppm/°C drift against stricter requirements that might necessitate higher-grade references from the same family or alternative manufacturers.

Voltage Reference Part Context

This part belongs to the LT1004 series of micropower voltage references. The LT1004 family includes various output voltage options and package types, such as the TO-92 and SOIC variants. The IPWR suffix specifically denotes the plastic TSSOP-8 surface-mount package with the 2.5V fixed output, distinguishing it from other voltage outputs or through-hole packages in the broader LT1004 lineup.
