REF5050AIDR

Overview

The REF5050AIDR is a fixed series voltage reference IC from Texas Instruments, providing a precise 5V 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 5.2V to 18V and supports a maximum output current of 10mA. With a supply current of 800µA, it delivers low noise performance (15µVpp from 0.1Hz to 10Hz). Packaged in an 8-pin SOIC, it functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Delivers high precision with ±0.05% initial accuracy and ultra-low drift of 3 ppm/°C for stable reference performance.
• Features low noise characteristics suitable for sensitive analog signal processing applications.
• Capable of both sourcing and sinking load current to accommodate diverse circuit requirements.

Applications

• High-precision data acquisition systems
• Industrial process control instrumentation
