REF5050AIDGKT

Overview

The REF5050AIDGKT is a fixed series voltage reference IC from Texas Instruments, providing a precise 5V output. It features an initial accuracy of ±0.1% and operates within an input voltage range of 5.2V to 18V. The device delivers up to 10mA of output current with a typical supply current of 1.2mA. Packaged in an 8-VSSOP surface-mount format, it ensures low noise performance with a 6µVpp characteristic between 0.1Hz and 10Hz. The unit supports operation across a wide temperature range from -40°C to +125°C.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial tolerance specifications.
• Features ultra-low noise characteristics suitable for sensitive analog signal processing applications.
• Provides robust thermal stability with minimal drift over the extended industrial temperature range.

Applications

• Precision data acquisition systems requiring stable reference voltages
• High-resolution analog-to-digital converter (ADC) front-end circuits
• Medical instrumentation and diagnostic equipment
• Industrial process control and monitoring systems

Procurement Notes

Verify the specific suffix GKT indicates tape-and-reel packaging when ordering. Confirm the 8-VSSOP package dimensions match your PCB footprint requirements. Ensure the 5.2V minimum input voltage constraint is met by your power supply design. Check for RoHS compliance status if required by your manufacturing standards. Validate that the ±0.1% accuracy grade meets your system's precision needs.

Selection Notes

Select this component when low noise and high accuracy are critical for maintaining signal integrity in precision measurement applications. The VSSOP package offers space efficiency for compact designs. Consider the 10mA drive capability for direct loading of ADC inputs or sensor bridges. Evaluate the 3ppm/°C temperature coefficient against environmental operating conditions to ensure long-term stability without external calibration.

Part Context

This part belongs to the REF50xx family of precision voltage references designed for demanding analog applications. The REF5050 variant specifically provides a 5V output, distinguishing it from other voltage options in the series. The A-grade designation indicates tighter initial accuracy compared to standard grades. The GKT suffix denotes the reel packaging format for automated assembly processes.

Replacement Considerations

REF5050AIDR is a pin-compatible alternative in SOIC-8 packaging. REF5050AIDGKR serves as another VSSOP option with potentially different noise specifications. Verify electrical parameters and package dimensions before substitution to ensure circuit compatibility.
