Overview
The REF5050AIDG4 is a precision series voltage reference from Texas Instruments, housed in an 8-pin SOIC package. It delivers 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 reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Provides high-precision voltage referencing with low noise and very low drift characteristics for stable performance.
- Capable of both sourcing and sinking current, ensuring excellent line and load regulation capabilities.
- Utilizes proprietary design technology to achieve superior temperature stability and high initial accuracy.
Applications
- High-precision data acquisition systems
- Industrial process control instrumentation
- Medical equipment requiring stable reference voltages
Procurement Notes
Verify the specific suffix 'DG4' against the manufacturer's latest documentation to confirm compliance status and availability, as this indicates a lead-free variant. Ensure the ordering part number matches the required package style and grade. Confirm that the component meets all necessary regulatory standards for the intended application environment before finalizing procurement.
Selection Notes
Select the REF5050AIDG4 when a fixed 5 V output is required with tight tolerance specifications. This component is suitable for designs needing low drift over wide temperature ranges. Consider the SOIC-8 package constraints and ensure the power supply input remains within the specified maximum limits to maintain optimal regulation and performance.
Part Context
This component belongs to the REF50xx family of precision voltage references manufactured by Texas Instruments. The family utilizes series topology to provide stable outputs. The REF5050 specifically offers a 5 V nominal output. The DG4 suffix denotes a lead-free version compliant with RoHS directives, distinguishing it from standard commercial variants.
Replacement Considerations
The REF5050AIDRG4 is a verified equivalent part number representing the same functional specifications and package type. Verify pinout compatibility and thermal characteristics when substituting.
