REF7012QDGKR

Overview

The REF7012QDGKR is an ultra-high-precision series voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.025%. The device features a temperature coefficient of 2 ppm/°C and supports a maximum input voltage of 18 V. It operates within a junction current range up to 6 mA and functions reliably across a temperature range of -40°C to +125°C. The component is housed in a VSSOP-8 surface-mount package.

Feature Summary

• Ultra-high precision performance with low drift characteristics
• Series topology for stable regulation
• Automotive qualification compliant

Applications

• High-resolution data acquisition systems
• Precision instrumentation
• Medical equipment requiring stable references

Procurement Notes

Verify the specific suffix QDGKR against official Texas Instruments documentation to confirm automotive grade status and packaging details. Ensure compatibility with your PCB footprint for the VSSOP-8 package. Cross-reference the datasheet for thermal management requirements under maximum load conditions.

Selection Notes

Select this component when applications demand minimal long-term drift and high initial accuracy. The 2.5 V output suits interfaces requiring mid-rail references. Consider the VSSOP-8 package size constraints and the 18 V input tolerance for system design flexibility.

Part Context

This part belongs to the REF70 family of voltage references, designed for demanding analog signal chain applications. The 'Q' designation indicates automotive qualification, ensuring reliability in harsh environments. It complements other precision components in high-end measurement and control systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the REF70 series or other TI ultra-low drift references. Verify that substitute parts meet the same 2 ppm/°C temperature coefficient and 0.025% initial accuracy specifications.
