Low-Noise, Very Low Drift, Precision

VOLTAGE REFERENCE

FEATURES

DESCRIPTION

•

LOW TEMPERATURE DRIFT:

The REF50xx is a family of low-noise, low-drift, very

high precision voltage references. These references

are capable of both sinking and sourcing, and are

very robust with regard to line and load changes.

–

High-Grade: 3ppm/°C (max)

Standard-Grade: 8ppm/°C (max)

•

HIGH ACCURACY:

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 REF50xx family ideal for use

in high-precision data acquisition systems.

–

High-Grade: 0.05% (max)

Standard-Grade: 0.1% (max)

•

LOW NOISE: 3µV_PP/V

HIGH OUTPUT CURRENT: ±10mA

TEMPERATURE RANGE: –40°C to +125°C

Each reference voltage is available in both standard-

and high-grade versions. They are offered in

MSOP-8⁽³⁾and SO-8 packages, and are specified

from –40°C to +125°C.
