Overview
The REF5020AIDGKT is a low-noise, very low drift precision voltage reference IC from Texas Instruments. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±0.1%. The device operates within an input voltage range of 2.25 V to 18 V and delivers up to 10 mA of output current. It features a temperature coefficient of 8 ppm/°C and line regulation of 1 ppm/V. The component is housed in an 8-pin VSSOP package and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Provides stable fixed reference voltage with high initial accuracy
- Features low noise performance for sensitive analog applications
- Exhibits very low drift characteristics over temperature variations
Applications
- High-resolution data acquisition systems
- Precision instrumentation amplifiers
- Medical equipment requiring stable references
Procurement Notes
Verify the specific suffix (e.g., GKT) against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the required output voltage matches the part number variant, as the REF5020 series includes multiple voltage options. Confirm that the operating environment stays within the specified -40°C to +125°C range for optimal performance.
Selection Notes
Select this component when low noise and minimal drift are critical for system accuracy. The 2.048 V output is suitable for ADCs and DACs with standard reference inputs. Consider the 10 mA drive capability for driving moderate loads without external buffering. The VSSOP-8 package offers space efficiency for compact designs.
Part Context
This part belongs to the REF5020 family of precision voltage references designed for high-performance applications. It complements other Texas Instruments reference solutions by offering a balance of low noise, low drift, and moderate output current in a small surface-mount package.
Replacement Considerations
Check for direct pin-compatible substitutes within the same family or similar precision classes. Verify that alternative parts meet the same noise, drift, and current requirements.
