REF6130IDGKR

Overview

The REF6130IDGKR is a high-precision series voltage reference manufactured by Texas Instruments, housed in an 8-pin VSSOP package. It provides a fixed output voltage of 3V with an initial accuracy of 0.05% and a temperature coefficient of 8 ppm/°C. The device operates within a supply voltage range of 2.3V to 5.5V and supports a load current up to 10mA. It functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Integrated low-noise bandgap reference core for stable DC output
• High precision performance with tight initial accuracy tolerance
• Low temperature drift characteristics for thermal stability
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• Medical instrumentation signal conditioning circuits
• Industrial process control measurement systems

Procurement Notes

Verify the specific suffix 'KR' indicates cut-tape packaging rather than reel-only when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to the sensitive semiconductor nature of the component. Cross-reference the datasheet revision date to ensure compatibility with design specifications.

Selection Notes

Select this component when a 3V reference is required with moderate noise performance and high accuracy. Compare against the REF6230 if lower temperature coefficients are needed, or the REF5030 for different noise profiles. Consider the REF6150 if a 5V output is preferred. Evaluate power consumption requirements against the quiescent current specifications provided in the technical data.

Part Context

This part belongs to the REF61xx family of high-precision voltage references from Texas Instruments. It shares the same VSSOP-8 footprint and general functionality as other members like the REF6133 and REF6150, differing primarily in output voltage and specific noise characteristics. It serves as a fundamental building block for precision analog front ends.

Replacement Considerations

Direct pin-compatible alternatives include the REF6133 (3.3V output) and REF6150 (5V output) from the same series. For lower noise applications, consider the REF62xx series. Verify that any substitute maintains the same 8-VSSOP package and operating temperature range.
