REF50xx Low-Noise, Very Low Drift, Precision
Voltage Reference
1 Features 3 Description
The REF50xx is a family of low-noise, low-drift, very
1
• Low Temperature Drift:
high precision voltage references. These references
– High-Grade: 3 ppm/°C (Maximum)
are capable of both sinking and sourcing current, and
– Standard-Grade: 8 ppm/°C (Maximum)
have excellent line and load regulation.
• High Accuracy:
Excellent temperature drift (3 ppm/°C) and high
– High-Grade: 0.05% (Maximum)
accuracy (0.05%) are achieved using proprietary
design techniques. These features, combined with
– Standard-Grade: 0.1% (Maximum)
very low noise, make the REF50xx family ideal for
• Low Noise: 3 μV

use in high-precision data acquisition systems.
• Excellent Long-term Stability:
Each reference voltage is available in both standard-
– 45 ppm/1000 hr (typ) after 1000 Hours
and high-grade versions. They are offered in MSOP-8
• High-Output Current: ±10 mA
and SO-8 packages, and are specified from –40°C to
125°C.
• Temperature Range: –40°C to 125°C
