REF5050AIDGKR

Overview

The REF5050AIDGKR is a fixed series voltage reference IC from Texas Instruments, providing a nominal output of 5 V. It features an initial accuracy of ±0.1% and operates within an input voltage range of 5.2 V to 18 V. The device delivers a maximum output current of 10 mA with a supply current of 1.2 mA. It exhibits a temperature coefficient of 8 ppm/°C and low noise characteristics of 15 µVpp/V in the 0.1 Hz to 10 Hz band. Packaged in an 8-VSSOP surface-mount format, it supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides high-precision fixed voltage reference with low drift characteristics
• Capable of both sourcing and sinking load current for flexible circuit integration
• Features low noise performance suitable for sensitive analog signal paths

Applications

• High-resolution data acquisition systems
• Precision analog-to-digital converter (ADC) references
• Medical instrumentation requiring stable voltage sources

Procurement Notes

Verify the specific suffix 'GKR' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the ±0.1% accuracy grade meets system requirements, as higher precision grades like 'ID' exist within the same family. Ensure the 8-VSSOP package dimensions align with the target PCB footprint design constraints.

Selection Notes

Select this component when a 5 V reference is required with moderate precision and low power consumption. The 8-VSSOP package offers space efficiency compared to larger SOIC options. Consider the 8 ppm/°C temperature coefficient against stricter application needs where lower drift variants may be necessary.

Part Context

This part belongs to the REF50xx family of precision voltage references designed for demanding applications. The family utilizes proprietary technology to achieve low noise and stability. The REF5050 specifically targets the 5 V output segment, offering a balance between performance and power usage for industrial and measurement equipment.

Replacement Considerations

REF5050AIDR provides equivalent electrical specifications in an 8-SOIC package. REF5050AIDGKT offers the same performance in an 8-VSSOP package with different reel quantities.
