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.
