Overview
The REF5025ID is a precision series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±0.05%. The device operates within an input voltage range of 2.7V to 18V and draws a supply current of 1.2mA. It features a low temperature coefficient of 3ppm/°C and exhibits a noise level of 7.5µVpp/V in the 0.1Hz to 10Hz frequency band. The component supports a maximum output current of 10mA and functions reliably across a temperature range of -40°C to 125°C. It is housed in an 8-SOIC surface-mount package.
Feature Summary
- Delivers high-precision voltage regulation with tight initial accuracy tolerance for critical measurement applications.
- Maintains stable performance over wide temperature variations through a low temperature coefficient design.
- Provides low-noise output characteristics suitable for sensitive analog signal processing circuits.
Applications
- Medical ECG systems requiring precise reference voltages
- High-resolution data acquisition systems
- Precision instrumentation and sensor interfaces
Procurement Notes
Verify the specific suffix 'ID' corresponds to the 8-SOIC package variant when sourcing. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Ensure the supplier provides valid traceability for the Texas Instruments manufacturing origin. Check for any recent Product Change Notifications regarding assembly or material updates before finalizing procurement orders.
Selection Notes
Select this component when strict accuracy requirements demand an initial tolerance better than standard commercial references. The 8-SOIC package offers a compact footprint for space-constrained designs. Consider the 1.2mA supply current for power-sensitive applications. Verify that the 10mA output drive capability meets the load requirements of the downstream circuitry without exceeding thermal limits.
Part Context
This part belongs to the REF50xx family of precision voltage references from Texas Instruments. The family includes variants with different output voltages and accuracy grades, such as the REF5025AIDR which offers ±0.1% accuracy. The REF5025ID represents the higher precision tier within the 2.5V output segment, designed for applications where long-term stability and low drift are paramount.
Replacement Considerations
No verified public substitute part numbers are available for direct replacement.
