FEATURES  
DESCRIPTION

•
LOW TEMPERATURE DRIFT:  
–
–
High-Grade: 3ppm/°C (max)  
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.  
Standard-Grade: 8ppm/°C (max)  
•
HIGH ACCURACY:  
–
–
High-Grade: 0.05% (max)  
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.  
Standard-Grade: 0.1% (max)  
•
•
•
LOW NOISE: 3μVPP/V  
HIGH OUTPUT CURRENT: ±10mA  
TEMPERATURE RANGE: –40°C to +125°C  
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.
