Overview
The REF5025IDG4 is a precision series voltage reference from Texas Instruments, providing a fixed output of 2.5V. It features an initial accuracy of ±0.05% and a temperature coefficient of 3 ppm/°C. The device operates within an input voltage range of 2.7V to 18V and supports a maximum load current of 10 mA. Supply current is typically 1.2 mA. It functions reliably across an extended temperature range of -40°C to +125°C. The component is housed in an 8-SOIC package with a width of 3.90 mm.
Feature Summary
- Delivers high-precision voltage regulation with low drift characteristics suitable for demanding measurement applications.
- Offers robust thermal stability through a very low temperature coefficient over the full industrial operating range.
- Provides significant output drive capability to support multiple downstream loads without external buffering.
Applications
- Medical ECG signal conditioning circuits
- High-resolution data acquisition systems
- Precision instrumentation front ends
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package dimensions match the 8-SOIC footprint requirements. Ensure the supply chain source provides valid traceability for the component's manufacturing origin and quality standards.
Selection Notes
Select this part when fixed 2.5V precision is required with tight initial accuracy tolerances. Consider the 10 mA output current limit against total system load requirements. Evaluate the 8-SOIC package constraints against available PCB real estate and thermal dissipation needs.
Part Context
This component belongs to the REF50xx family of precision voltage references designed for high-performance analog applications. It shares core architectural similarities with variants like the REF5025ID and REF5025AID, differing primarily in accuracy grades and packaging options within the same functional series.
Replacement Considerations
REF5025ID serves as a direct functional equivalent within the same product line. Verify pin compatibility and electrical parameter alignment before substitution.
