REF6125IDGKT

Overview

The REF6125IDGKT is a high-precision voltage reference from Texas Instruments, housed in an 8-VSSOP package. It provides a fixed output of 2.5 V with an initial accuracy of 0.05% and a temperature coefficient of 8 ppm/°C. The device operates within an input voltage range of 2.7 V to 36 V and supports a maximum load current of 3 mA. It functions across an extended industrial temperature range of -40°C to +125°C, consuming a typical supply current of 830 µA.

Feature Summary

• Integrated high-bandwidth buffer for direct ADC driving
• High precision with low drift characteristics
• Wide input voltage capability

Applications

• Data acquisition systems
• Industrial process control
• Medical instrumentation

Procurement Notes

Verify the specific suffix IDGKT corresponds to the tape-and-reel packaging format required for automated assembly. Confirm that the 8-VSSOP footprint matches the target PCB design. Ensure the component meets RoHS compliance standards for the intended market. Validate the operating temperature range against environmental specifications.

Selection Notes

Select this component when a buffered output is required to drive analog-to-digital converters directly without external amplification. The wide input voltage range allows flexibility in power supply design. Compare noise performance and quiescent current against unbuffered alternatives if power consumption is critical.

Part Context

This part belongs to the REF61xx family of high-precision voltage references featuring integrated buffers. It shares the same pinout and form factor as other variants in the series, such as the REF6133 and REF6150, differing primarily in output voltage and specific drift characteristics.

Replacement Considerations

Direct substitutes include REF6125IDGKR (reel version) and REF6125IDGKT.B. Other REF61xx variants may fit mechanically but require verification of output voltage compatibility.
