REF5025AIDRG4

Overview

The REF5025AIDRG4 is a low-noise, low-drift precision voltage reference from Texas Instruments. It provides a fixed output of 2.5 V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 8 ppm/°C. The device operates within an input voltage range of 2.7 V to 18 V and delivers up to 10 mA of output current while consuming 1.2 mA of supply current. It features a noise level of 7.5 µVpp/V in the 0.1 Hz to 10 Hz band. Packaged in an 8-SOIC surface-mount footprint, it supports operation from -40°C to +125°C.

Feature Summary

• Delivers high-precision voltage regulation with ±0.1% initial accuracy for stable reference performance.
• Maintains stability across temperature variations with a maximum drift of 8 ppm/°C.
• Supports bidirectional current flow, allowing both sourcing and sinking capabilities.
• Features ultra-low noise characteristics suitable for sensitive analog signal processing.

Applications

• High-resolution data acquisition systems
• Precision industrial process control instrumentation
• Medical diagnostic equipment requiring stable references

Procurement Notes

Verify the complete part number including suffixes such as 'G4' to ensure compliance with specific environmental standards like RoHS. Confirm package type matches design requirements. Check manufacturer documentation for moisture sensitivity levels and recommended soldering profiles to prevent damage during assembly.

Selection Notes

Select this component when a fixed 2.5 V reference is required with tight tolerance specifications. Consider the 8-SOIC package for surface-mount applications. Evaluate power consumption needs against the 1.2 mA supply current. Ensure input voltage remains within the 2.7 V to 18 V operational window for proper regulation.

Part Context

This part belongs to the REF50xx series of precision voltage references designed for demanding measurement applications. It utilizes proprietary design techniques to achieve low drift and noise. The 'G4' suffix indicates lead-free construction compliant with international environmental directives.

Replacement Considerations
