REF5010IDGKT

Overview

The REF5010IDGKT is a precision series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 10V with an initial accuracy tolerance of ±0.05%. The device operates within an input voltage range of 10.2V to 18V and draws a supply current of 1.2mA. It features a low temperature coefficient of 3ppm/°C and exhibits a peak-to-peak noise of 30µV in the 0.1Hz to 10Hz frequency band. The component is housed in an 8-VSSOP surface-mount package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial accuracy tolerance
• Maintains stable performance across wide industrial temperature ranges
• Provides low-noise characteristics suitable for sensitive analog signal chains

Applications

• High-resolution data acquisition systems requiring precise reference voltages
• Industrial process control instrumentation
• Medical equipment signal conditioning circuits

Procurement Notes

Verify the specific suffix DGKT indicates the tape-and-reel packaging format upon ordering. Confirm that the 8-VSSOP package dimensions align with the target PCB footprint. Ensure the input voltage supply remains strictly within the 10.2V to 18V operational window to maintain specified regulation and accuracy parameters.

Selection Notes

Select this component when a 10V fixed reference is required with superior long-term stability and low drift. The VSSOP package offers a compact solution for space-constrained designs. Consider the 1.2mA quiescent current for power budget calculations. Verify compatibility with downstream ADC or DAC inputs requiring this specific voltage level.

Part Context

This part belongs to the REF50xx family of low-noise, very low drift precision series voltage references from Texas Instruments. The REF5010 variant specifically targets applications demanding a 10V output. The IDGKT designation distinguishes it by its specific accuracy grade and reel packaging configuration compared to tube-packed or alternative package variants.

Replacement Considerations

Direct pin-compatible substitutes include other REF5010 variants such as REF5010IDR (SOIC package) or REF5010AIDR, provided the package type change is acceptable for the design.
