REF3430QDGKRQ1

Overview

The REF3430QDGKRQ1 is an automotive-grade series voltage reference from Texas Instruments, housed in a VSSOP-8 package. It provides a fixed output of 3 V with an initial accuracy of 0.05% and a temperature coefficient of 6 PPM/C. The device supports input voltages up to 12 V and can source a maximum shunt current of 10 mA. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Automotive qualification compliant for reliable operation in vehicle environments
• High precision performance with low drift characteristics over temperature
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• Automotive sensor signal conditioning
• Data acquisition systems requiring stable reference voltages
• Precision analog front-end circuits

Procurement Notes

Verify the specific suffix QDGKRQ1 matches the required VSSOP-8 package and automotive grade specifications. Confirm that the 3 V output and 0.05% accuracy align with system requirements. Ensure compatibility with the intended operating temperature range of -40°C to +125°C before finalizing procurement.

Selection Notes

Select this component when a high-precision, low-drift voltage reference is needed for automotive applications. The VSSOP-8 package offers a compact footprint compared to larger alternatives. Consider the 10 mA load capability and 12 V input range to ensure it meets the power budget and interface requirements of the target circuit design.

Part Context

This part belongs to the REF34xx family of precision voltage references designed for automotive use. It shares core electrical specifications with other variants in the series but differs in package type and specific ordering suffixes. The REF3430 variant specifically targets the 3 V output requirement within this product line.

Replacement Considerations

REF3430SQDBVRQ1 is a verified alternative offering identical electrical specifications in a SOT-23-6 package.
