REF7030QFKHT

Overview

The REF7030QFKHT is a high-precision series voltage reference from Texas Instruments, delivering a fixed output of 3.0 V. It features an initial accuracy of ±0.025% and a maximum temperature coefficient of 2 ppm/°C across the -40°C to +125°C range. The device operates with input voltages up to 18 V and provides ±10 mA output current. It utilizes a hermetically sealed LCCC-8 package for long-term stability.

Feature Summary

• Hermetically sealed ceramic LCCC package ensures humidity resistance and long-term stability without calibration
• Ultra-low noise performance enables precision measurements in sensitive analog front ends
• High power supply rejection ratio supports stable operation under varying line conditions
• Integrated shutdown mode reduces quiescent current when the device is not in use

Applications

• Semiconductor test equipment
• Precision data acquisition systems
• Ultrasound scanners
• X-ray systems
• Industrial instrumentation

Procurement Notes

Verify the specific suffix QFKHT confirms the hermetic LCCC-8 package and automotive-grade qualification status. Confirm the 3.0 V output variant matches system requirements. Check datasheet revision history for any updates to electrical characteristics or thermal metrics before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring low drift and high accuracy over wide temperature ranges. Ensure the input voltage meets the minimum dropout requirement relative to the 3.0 V output. Verify that the load current stays within the ±10 mA limit. Consider the LCCC package size constraints during PCB layout planning.

Part Context

This part belongs to the REF70 family of ultra-high-precision voltage references. It shares core architectural features with variants like REF7025 and REF7040 but differs in its fixed 3.0 V output voltage. The FKH suffix specifically denotes the hermetic ceramic package option, distinguishing it from the plastic VSSOP versions.

Replacement Considerations

REF7030QDGKR offers the same electrical performance in a non-hermetic VSSOP-8 package.
