The REF50xxA-Q1 family of devices is low-noise, low-drift, very-high precision-voltage reference. These reference devices 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 REF50xxA-Q1 family of devices ideal for use in high-precision data acquisition systems.
Each reference voltage is available in a standard-grade versions. The devices are offered in SO-8 packages and are specified from –40°C to 125°C.
