Overview
The REF5020AIDG4 is a precision series voltage reference IC manufactured by Texas Instruments. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±0.1%. The device features a temperature coefficient of 8 ppm/°C and operates within an input voltage range of 2.7 V to 18 V. It draws a supply current of 1.2 mA and supports a maximum load current of 10 mA. The component is housed in an 8-SOIC package and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Delivers a stable 2.048 V output with high initial accuracy for precise measurement systems.
- Features low temperature drift characteristics suitable for applications requiring long-term stability.
- Supports wide input voltage ranges up to 18 V for flexible power supply integration.
Applications
- High-resolution data acquisition systems
- Precision analog-to-digital converter (ADC) references
- Industrial process control instrumentation
Procurement Notes
Verify the specific suffix 'DG4' against the manufacturer's official documentation to confirm pinout compatibility and RoHS status. Ensure the selected package variant matches the PCB footprint requirements. Cross-reference the datasheet revision history for any updates regarding material composition or manufacturing site changes prior to final procurement.
Selection Notes
Select this component when a fixed 2.048 V reference with ±0.1% accuracy is required. Consider the 8 ppm/°C temperature coefficient for thermal stability needs. Verify that the 1.2 mA supply current fits the system's power budget. Confirm the SOIC-8 package dimensions align with the design constraints.
Part Context
This part belongs to the REF50xx family of precision voltage references from Texas Instruments. The family offers various output voltages and accuracy grades. The REF5020 variant specifically targets applications needing a 2.048 V output. The DG4 suffix typically indicates a lead-free, RoHS-compliant version of the standard REF5020AID package.
Replacement Considerations
Direct substitutes include other REF5020 variants such as REF5020AIDR or REF5020AIDT, depending on the required packaging format. Ensure the replacement maintains the same 2.048 V output and ±0.1% accuracy specifications.
