Overview

The REF5050AIDR is a low-noise, low-drift series voltage reference that provides a precision 5V output. It is designed for high-performance data acquisition systems, offering a high output current of up to 10 mA and excellent temperature stability. With a low supply current of 480 uA and a wide input voltage range up to 18V, it is a versatile choice for powering precision analog circuitry.

Why Choose This Part

The REF5050AIDR features an extremely low noise profile of 15uVpp/V and a tight initial tolerance of +/-0.1%. Its ability to source or sink 10 mA allows it to drive significant loads without the need for an external buffer, simplifying precision signal chain designs.

Applications
