REF5025AIDGKT

Overview

The REF5025AIDGKT is a precision series voltage reference IC manufactured by Texas Instruments, housed in an 8-VSSOP package. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±0.05%. The device features a low temperature coefficient of 3ppm/°C and operates within an input voltage range of 2.7V to 18V. It supports a maximum output current of 10mA while consuming a supply current of 1.2mA. The component functions reliably across a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Delivers high-precision voltage regulation with an initial accuracy of ±0.05% for critical measurement applications.
• Maintains stable performance over varying thermal conditions with a low temperature coefficient of 3ppm/°C.
• Supports bidirectional current flow, allowing both sourcing and sinking capabilities up to 10mA.

Applications

• High-resolution data acquisition systems
• Precision analog-to-digital converter (ADC) references
• Medical instrumentation requiring stable voltage sources

Procurement Notes

Verify the specific suffix 'GKT' corresponds to the 8-VSSOP package and tape-and-reel packaging configuration. Confirm that the ±0.05% accuracy grade matches the design requirements, as other variants in the REF5025 family offer different tolerances. Ensure the 18V maximum input voltage rating aligns with the system power supply rails.

Selection Notes

Select this component when superior long-term stability and low noise are required alongside tight initial accuracy. The VSSOP package offers a compact footprint suitable for space-constrained designs. Consider the 1.2mA supply current consumption against battery-operated constraints, noting that lower current alternatives exist within the broader product family if absolute precision is less critical.

Part Context

This part belongs to the REF5025 series of precision voltage references designed for high-performance applications. The series utilizes proprietary technology to achieve low drift and low noise characteristics. The REF5025AIDGKT specifically represents the A-grade accuracy variant packaged in a small-outline vertical leadless package, distinguishing it from standard SOIC or higher-drift versions.

Replacement Considerations

REF5025IDGKT: Offers identical electrical specifications and pinout but may differ in initial accuracy grading or manufacturing lot specifications.
