REF6025IDGKR

Overview

The REF6025IDGKR is a high-precision voltage reference from Texas Instruments, featuring an integrated ADC drive buffer. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.05% and a temperature coefficient of 3 ppm/°C. The device operates within an input voltage range of 2.7 V to 18 V and supports a maximum load current of 10 mA. It functions reliably across an extended temperature range from -40°C to +125°C. Packaged in an 8-pin VSSOP (DGK) surface-mount case, it draws a typical supply current of 1.2 mA.

Feature Summary

• Integrated ADC drive buffer for direct interfacing with analog-to-digital converters
• High precision with low drift characteristics over temperature variations
• Wide input voltage capability supporting various power supply configurations

Applications

• Data acquisition systems requiring stable reference voltages
• Industrial process control instrumentation
• Medical equipment signal conditioning circuits
• Precision sensor interfaces

Procurement Notes

Verify the specific suffix IDGKR corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-VSSOP package dimensions align with the target PCB footprint design. Ensure the component meets RoHS compliance standards applicable to the final product deployment region. Cross-reference the manufacturer date code to ensure freshness and reliability.

Selection Notes

Select this component when a compact solution combining a precision reference with an output buffer is necessary. It is suitable for designs where board space is limited but high accuracy and low noise are critical. Consider the 10 mA output current capability against the specific loading requirements of the downstream ADC or amplifier stage to ensure optimal performance without exceeding specifications.

Part Context

This part belongs to the REF60xx family of high-precision voltage references manufactured by Texas Instruments. The series is designed to offer superior stability and lower noise compared to standard references. The integration of a drive buffer distinguishes it from basic reference diodes, simplifying circuit design by eliminating the need for external buffering components while maintaining high accuracy.
