REF5050IDG4

Overview

The REF5050IDG4 is a fixed voltage reference IC from Texas Instruments, providing a precise 5 V output. It features an initial accuracy of ±0.05% and a temperature coefficient of 3 ppm/°C. The device operates within an input voltage range of 5.2 V to 18 V and supports an output current of 10 mA. It utilizes a series topology with line regulation of 1 ppm/V and load regulation of 30 ppm/mA. The component is housed in an 8-pin SOIC package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Delivers high precision with an initial accuracy of ±0.05% and low temperature drift of 3 ppm/°C for stable reference performance.
• Features robust line and load regulation capabilities to maintain output stability under varying supply and load conditions.
• Capable of sourcing and sinking current up to 10 mA, offering flexibility in circuit design.

Applications

• High-precision data acquisition systems
• Calibration equipment requiring stable voltage references
• Industrial process control instrumentation

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free construction as per Texas Instruments standards. Confirm the package type matches the required PCB footprint, specifically the 8-pin SOIC dimensions. Ensure the operating environment stays within the specified -40°C to +125°C range to maintain the stated accuracy and drift specifications.

Selection Notes

Select this component when a fixed 5 V reference with high accuracy (±0.05%) and low drift (3 ppm/°C) is required. It is suitable for applications needing both source and sink current capabilities up to 10 mA. Consider the 8-pin SOIC package for surface-mount assembly. Verify that the input voltage remains between 5.2 V and 18 V for proper operation.

Part Context

The REF5050IDG4 belongs to the REF5050 family of precision voltage references from Texas Instruments. This series is designed for applications demanding high accuracy and low noise. The 'ID' designation typically refers to the industrial temperature grade and higher accuracy bin, while 'G4' denotes the Green/RoHS-compliant packaging variant.

Replacement Considerations

Check for direct replacements within the REF5050 family, such as REF5050ID or REF5050AID, noting differences in accuracy grades. Other compatible parts may include REF50xx series variants with similar pinouts and electrical characteristics.
