LT1004CDR-1-2

Voltage Reference Overview

The LT1004CDR-1-2 is a micropower integrated precision voltage reference manufactured by Texas Instruments. It provides a stable 1.2 V output with an initial accuracy of 0.8% and a temperature coefficient of 20 ppm/°C. The device operates within a supply voltage range of 2.5 V to 36 V and supports a maximum shunt current of 20 mA. It functions across a temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package.

Voltage Reference Feature Summary

• Provides a fixed 1.2 V precision reference output
• Operates over a wide input voltage range up to 36 V
• Features low temperature drift for thermal stability
• Designed for micropower applications

Voltage Reference Applications

• Portable instrumentation systems
• Battery-powered measurement devices
• Data acquisition systems requiring stable references
• Precision analog-to-digital converter biasing

Voltage Reference Procurement Notes

Verify the specific suffix indicates the 1.2 V output variant, as the base LT1004 series includes other voltages. Confirm the SOIC-8 package matches your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for RoHS compliance status if required by your manufacturing standards. Validate that the 20 mA shunt current capability aligns with your circuit load design.

Voltage Reference Selection Notes

Select this component when a stable 1.2 V reference is needed in space-constrained designs. It is suitable for applications where power consumption must be minimized while maintaining accuracy. Consider the 20 ppm/°C drift if high thermal stability is critical. Compare against series references if adjustable voltage is required instead of a fixed output.

Voltage Reference Part Context

This part belongs to the LT1004 family of micropower integrated voltage references from Texas Instruments. The family offers various fixed output voltages including 1.2 V, 2.5 V, and 12 V options. These references are designed for high precision and low power consumption in portable and industrial applications.
