FEATURES  
DESCRIPTION  
2
Qualified for Automotive Applications  
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.  
Low Temperature Drift  
High Grade: 3 ppm/°C (max)  
Standard Grade: 8 ppm/°C (max)  
Excellent temperature drift (3 ppm/°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.  
High Accuracy  
High Grade: 0.05% (max)  
Standard Grade: 0.1% (max)  
Low Noise: 3 µVPP/V  
Each reference voltage is available in both standard-  
and high-grade versions. They are offered in SO-8  
packages and are specified from –40°C to 125°C.  
High Output Current: ±10 mA  
Temperature Range: –40°C to 125°C
