FEATURES
DESCRIPTION

LOW TEMPERATURE DRIFT:
The REF50xx is a family of low-noise, low-drift, very
high precision voltage references. These references
–
High-Grade: 3ppm/°C (max)
are capable of both sinking and sourcing, and are
–
Standard-Grade: 8ppm/°C (max)
very robust with regard to line and load changes.
HIGH ACCURACY:
Excellent
temperature
drift
(3ppm/°C)
and
high
–
High-Grade: 0.05% (max)
accuracy (0.05%) are achieved using proprietary
–
Standard-Grade: 0.1% (max)
design techniques. These features, combined with
very low noise, make the REF50xx family ideal for
LOW NOISE: 3mVPP/V
use in high-precision data acquisition systems.
EXCELLENT LONG-TERM STABILITY:
Each reference voltage is available in both standard-
–
5ppm/1000hr (typ) after 1000 hours
and high-grade versions. They are offered in MSOP-8
HIGH OUTPUT CURRENT: ±10mA
and SO-8 packages, and are specified from –40°C to
TEMPERATURE RANGE: –40°C to +125°C
+125°C.
