FEATURES

DESCRIPTION

• LOW TEMPERATURE DRIFT:

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

high precision voltage references. These references

– High-Grade: 3ppm/°C (max)

are capable of both sinking and sourcing, and are

– Standard-Grade: 8ppm/°C (max)

very robust with regard to line and load changes.

• HIGH ACCURACY:

Excellent temperature drift (3ppm/°C) and high

– High-Grade: 0.05% (max)

accuracy (0.05%) are achieved using proprietary

– Standard-Grade: 0.1% (max)

design techniques. These features, combined with

very low noise, make the REF50xx family ideal for

• LOW NOISE: 3mV

use in high-precision data acquisition systems.

• EXCELLENT LONG-TERM STABILITY:

Each reference voltage is available in both standard-

– 5ppm/1000hr (typ) after 1000 hours

and high-grade versions. They are offered in MSOP-8

• HIGH OUTPUT CURRENT: ±10mA

and SO-8 packages, and are specified from –40°C to

• TEMPERATURE RANGE: –40°C to +125°C

+125°C.
