REF5050AID

Overview

The REF5050AID is a fixed series voltage reference integrated circuit manufactured by Texas Instruments. It provides a precise 5 V output with an initial accuracy of ±0.05%. The device operates within an input voltage range of 5.2 V to 18 V and supports a maximum load current of 10 mA. It features a low temperature coefficient of 3 ppm/°C and line regulation of 1 ppm/V. The component is housed in an 8-pin SOIC surface-mount package and functions reliably across a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial accuracy tolerance
• Maintains stable performance over wide temperature variations with minimal drift
• Supports moderate load currents for driving downstream analog circuits

Applications

• Precision data acquisition systems requiring stable reference voltages
• High-resolution analog-to-digital converter (ADC) front-end conditioning
• Industrial sensor signal conditioning interfaces

Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation, as variants such as AIDG4 or AIDR may differ in packaging or RoHS compliance status. Confirm the active lifecycle status directly with the manufacturer or authorized distributors, as availability and production status can change without public notice. Ensure the selected package matches the intended PCB footprint requirements.

Selection Notes

Select this component when a fixed 5 V reference with superior long-term stability and low temperature drift is required. The ±0.05% initial accuracy makes it suitable for applications demanding high measurement precision. Consider the 10 mA output capability to ensure sufficient drive strength for the connected load while maintaining regulation within specified limits.

Part Context
