LT1004CDRG4-2-5

Voltage Reference Overview

The LT1004CDRG4-2.5 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 maximum shunt current of 20 mA. Its temperature coefficient is specified at 20 ppm/°C. The component is housed in an 8-pin TSSOP package and is RoHS compliant.

Voltage Reference Feature Summary

• Provides a stable 2.5 V reference output suitable for precision applications
• Designed for low power consumption with micropower operation capabilities
• Ensures high precision through tight initial accuracy specifications

Voltage Reference Applications

• Portable battery-powered instrumentation systems
• Data acquisition systems requiring stable reference voltages
• Precision analog-to-digital converter (ADC) reference sources

Voltage Reference Procurement Notes

Verify the specific suffix '-2.5' confirms the 2.5 V output variant, as the base LT1004 series includes other voltage options. Confirm the 'CDRG4' designation indicates the tape-and-reel packaging format and lead-free composition. Ensure the TSSOP-8 package matches your PCB footprint requirements. Check for any recent product change notifications regarding pinout or electrical parameter updates from Texas Instruments.

Voltage Reference Selection Notes

Select this component when a fixed 2.5 V reference is required with moderate precision (0.8%) and low power constraints. It is suitable for applications where space is limited due to its small TSSOP-8 package. Consider alternative parts if higher accuracy or lower temperature coefficients are needed, as this part offers standard performance for general-purpose micropower references.

Voltage Reference Part Context

The LT1004 series belongs to Texas Instruments' family of micropower integrated voltage references. These devices are designed to replace zener diodes in low-power applications, offering superior stability and lower noise. The LT1004CDRG4-2.5 specifically utilizes the CDGR4 suffix to denote commercial temperature range operation and reel packaging, distinguishing it from tube-packed or industrial-grade variants.
