The REF50xx is a family of low-noise, low-drift, very high precision voltage references.
These references are capable of both sinking and sourcing current, and have excellent line and load
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.
Each reference voltage is available in both high grade (REF50xxIDGK and REF50xxID) and
standard grade (REF50xxAIDGK and REF50xxAID). The reference voltages are offered in 8-pin VSSOP and
SOIC packages, and are specified from –40°C to 125°C.
