Overview
The REF5050MDREP is a low-noise, very low drift, precision voltage reference from Texas Instruments. It provides a fixed output of 5 V with an initial accuracy of ±0.05% and a temperature coefficient of 3 ppm/°C. The device operates within an input voltage range up to 18 V and supports a maximum shunt current of 10 mA. It functions in extended industrial temperatures from -55°C to +125°C with a quiescent current of 800 µA. Packaged in an 8-SOIC case, it is designated as an Enhanced Product (EP) variant.
Feature Summary
- Enhanced Product (EP) qualification for high reliability applications
- Low noise performance suitable for sensitive analog circuits
- Very low drift characteristics ensuring long-term stability
Applications
- High-precision data acquisition systems
- Medical instrumentation requiring stable references
- Industrial process control sensors
Procurement Notes
Verify the Enhanced Product (EP) designation and specific suffix codes against the official datasheet to ensure compliance with reliability standards. Confirm package type and operating temperature range match design requirements. Check for obsolescence notices or lifecycle status updates directly from Texas Instruments before finalizing procurement plans.
Selection Notes
Select this component when enhanced reliability and low drift are critical compared to standard commercial grades. Ensure the 8-SOIC package fits the PCB layout constraints. Verify that the 5 V output aligns with system reference needs and that the 10 mA load capability meets circuit demands without exceeding thermal limits.
Part Context
The REF5050 series belongs to Texas Instruments' portfolio of precision voltage references designed for high-performance analog applications. The MDREP variant specifically denotes the Enhanced Product version, offering improved reliability metrics over standard commercial parts while maintaining the same electrical specifications as the base REF5050 model.
Replacement Considerations
Consult the official TI replacement matrix for verified substitutes. Standard REF5050 variants may serve as functional equivalents if EP reliability is not required.
