LT1004IDR-2-5

Voltage Reference Overview

The LT1004IDR-2.5 is a micropower integrated precision voltage reference manufactured by Texas Instruments, housed in an 8-pin SOIC surface-mount package. 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 supply voltage range up to 36 V and supports a maximum shunt current of 20 mA. It functions reliably across an industrial temperature range from -40°C to +85°C.

Voltage Reference Feature Summary

• Provides a stable 2.5 V reference output suitable for precision applications
• Features low power consumption characteristics for battery-operated systems
• Offers high initial accuracy and low temperature drift for signal integrity

Voltage Reference Applications

• Portable instrumentation requiring low power references
• Battery-powered measurement devices
• Data acquisition systems needing stable voltage sources

Voltage Reference Procurement Notes

Verify the specific suffix 'DR' confirms the SOIC-8 tape-and-reel packaging configuration. Ensure the '-2.5' designation matches the required 2.5 V output voltage for your circuit design. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Check for any specific handling requirements associated with the surface-mount technology package.

Voltage Reference Selection Notes

Select this component when a compact, low-power shunt reference is needed for 2.5 V applications. It is appropriate for designs where space constraints favor the SOIC-8 package over larger through-hole options. Consider its 20 ppm/°C temperature coefficient against stricter stability requirements that might necessitate higher-grade references like the LT1009 series.

Voltage Reference Part Context

This part belongs to the LT1004 family of micropower voltage references designed for cost-sensitive and power-constrained applications. It serves as a fundamental building block for analog circuits requiring a reliable voltage baseline. The device complements other Texas Instruments precision components used in sensor interfaces and signal conditioning chains.

Voltage Reference Replacement Considerations

LT1009IDR: Offers higher accuracy (0.4%) but consumes more current and has a different temperature coefficient.
