• Qualified for Automotive Applications
high precision-voltage references. These references
• Low Temperature Drift
are capable of both sinking and sourcing, and are
– Standard Grade: 8 ppm/°C (max)
very robust with regard to line and load changes.
• High Accuracy
Excellent temperature drift (3 ppm/°C) and high
– Standard Grade: 0.1% (max)
accuracy (0.05%) are achieved using proprietary
design techniques. These features combined with
• Low Noise: 3 μV
PP
/V
very low noise make the REF50xx family ideal for use
• EXCELLENT LONG-TERM STABILITY:
in high-precision data acquisition systems.
– 5 ppm/1000 hr (typ) after 1000 hours
Each reference voltage is available in a standard-
• High Output Current: ±10 mA
grade versions. The devices are offered in SO-8
• Temperature Range: –40°C to 125°C
packages and are specified from –40°C to 125°C.
