Overview
The REF6125IDGKR 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 0.02%. The device exhibits a low temperature coefficient of 3 ppm/°C and supports a maximum input voltage of 48 V. Operating within a junction temperature range of -40°C to +125°C, it consumes a typical supply current of 700 µA. The component is housed in an 8-pin VSSOP package.
Feature Summary
- Integrated ADC drive buffer for direct interfacing with analog-to-digital converters
- High precision performance with low drift characteristics
- Wide input voltage capability supporting various power supply configurations
Applications
- Precision data acquisition systems
- Industrial process control instrumentation
- Medical equipment requiring stable reference voltages
Procurement Notes
Verify the specific suffix IDGKR corresponds to the VSSOP-8 tape and reel packaging configuration. Confirm that the integrated buffer functionality aligns with system requirements, as this distinguishes the part from standard references. Ensure compatibility with the target PCB footprint and reflow soldering profiles specified in the official datasheet.
Selection Notes
Select this component when both high accuracy and low noise are critical for driving ADC inputs directly. The integrated buffer eliminates the need for external operational amplifiers, reducing board space and component count. Consider the 3 ppm/°C drift specification against environmental temperature variations in the application environment.
Part Context
This part belongs to the REF61xx family of high-precision voltage references designed for demanding applications. Unlike basic references, the REF6125 includes an on-chip buffer to maintain stability under capacitive loads. It serves as a key component in signal chains where reference integrity directly impacts measurement resolution.
Replacement Considerations
The REF6125IDGKT is a pin-compatible alternative in a tube package. Other members of the REF61xx series may offer different output voltages or buffer configurations.
