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.
Excellent temperature drift (3ppm/°C) and high
accuracy (0.05%) are achieved using proprietary
design techniques. These features, combined with
very-low noise make the REF50xx family ideal for use
in high-precision data acquisition systems.
Each reference voltage is available in both standard-
and high-grade versions. They are offered in MSOP-8
(available Q3, 2007) and SO-8 packages, and are
specified from –40°C to +125°C.
