3 Description
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 (3 ppm/°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 standardgrade
versions. The devices are offered in SO-8
packages and are specified from –40°C to 125°C.
