DESCRIPTION
The REF5025 is a low-noise, low-drift, very high precision voltage reference. This reference is capable of both
sinking and sourcing, and is very robust with regard to line and load changes.
Temperature drift (40 ppm/°C) from –55°C to 210°C is achieved using proprietary design techniques. These
features combined with very low noise make the REF5025 ideal for use in down-hole drilling applications.
