•

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

use in high-precision data acquisition systems.

•

Excellent Long-term Stability:

Each reference voltage is available in both standard-

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
