DESCRIPTION
The REF50xx is a family of low-noise, low-drift, very
high precision voltage references. These references
are capable of both sinking and sourcing, and are
very robust with regard to line and load changes.

design techniques. These features, combined with
very-low noise make the REF50xx family ideal for use
in high-precision data acquisition systems.
