REF6130IDGKT

Overview

The REF6130IDGKT is a high-precision series voltage reference from Texas Instruments, delivering a fixed output of 3 V. It features an initial accuracy of 0.05% and a temperature coefficient of 8 ppm/°C. The device operates within a supply voltage range of 2.7 V to 5.5 V and draws a typical quiescent current of 830 µA. It includes an integrated low-output impedance buffer and an enable pin for power management. The component is housed in an 8-pin VSSOP package and supports operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrated low-output impedance buffer ensures stable performance under varying load conditions
• Dedicated enable pin allows for effective power management and shutdown control
• High precision characteristics with low temperature drift for accurate signal conditioning

Applications

• Precision data acquisition systems requiring stable reference voltages
• Industrial process control instrumentation
• Medical equipment requiring high accuracy analog front ends

Procurement Notes

Verify the specific suffix IDGKT corresponds to the VSSOP-8 package and tape-and-reel shipping format. Confirm that the operating environment remains within the specified -40°C to +125°C range to maintain the 8 ppm/°C temperature coefficient specification. Ensure supply voltage does not exceed the maximum rating of 5.5 V to prevent device damage.

Selection Notes

Select this component when a fixed 3 V reference is required with high accuracy and low noise. The integrated buffer eliminates the need for external op-amps, simplifying board layout. Consider the 830 µA quiescent current against system power budgets. The VSSOP-8 package offers a compact solution for space-constrained designs compared to larger through-hole alternatives.

Part Context

This part belongs to the REF6130 family of high-precision voltage references. It shares the same core architecture as other variants in the series but is specifically configured for a 3 V output. The IDGKT designation indicates the specific thermal and mechanical packaging details provided by Texas Instruments for surface-mount assembly.

Replacement Considerations

Direct substitutes include other Texas Instruments parts from the same family with different output voltages or temperature coefficients, such as the REF6130IDGKR for reel variations. Cross-brand replacements require matching the 3 V output, 8 ppm/°C drift, and VSSOP-8 footprint.
