LT1004CDR-2-5

Voltage Reference Overview

The LT1004CDR-2-5 is a micropower integrated voltage reference manufactured by Texas Instruments. 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 +125°C and supports a maximum shunt current of 20 mA. It is housed in an 8-pin SOIC package.

Voltage Reference Feature Summary

• Micropower integrated design for low power consumption
• Fixed 2.5 V output voltage
• High precision with 0.8% initial accuracy
• Low temperature drift of 20 ppm/°C

Voltage Reference Applications

• Battery-powered instrumentation
• Data acquisition systems
• Portable test equipment
• Precision analog circuits requiring stable references

Voltage Reference Procurement Notes

Verify the specific suffix 'CDR' indicates the tape-and-reel packaging format and commercial grade temperature range. Confirm the '-2-5' designation corresponds to the 2.5 V output variant. Ensure compatibility with existing PCB footprints for the SOIC-8 package. Check for any recent lifecycle status updates or obsolescence notices from the manufacturer before finalizing procurement plans.

Voltage Reference Selection Notes

Select this component when a stable, low-power voltage reference is required for battery-operated applications. The 2.5 V output is suitable for driving ADCs and DACs directly. Consider the 0.8% initial accuracy and 20 ppm/°C drift for precision requirements. The SOIC-8 package offers a compact solution for space-constrained designs compared to larger through-hole options.

Voltage Reference Part Context

The LT1004 series represents Texas Instruments' micropower voltage reference family, designed for high precision and low power consumption. This specific model integrates the reference circuitry into a small surface-mount package, making it ideal for modern electronic designs where size and efficiency are critical factors.
