NOTES: REF5010, REF5020 REF5025, REF5030 REF5040, REF5045, REF5050 www.ti.com SBOS410E – JUNE 2007 – REVISED JUNE 2010 Low-Noise, Very Low Drift, Precision VOLTAGE REFERENCE Check for Samples: REF5010, REF5020, REF5025, REF5030, REF5040, REF5045, REF5050 1 FEATURES DESCRIPTION 2 • 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: 3mVPP/V 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.
