REF5020

低噪声、极低漂移、高精度电压基准

The REF50xx is a family of low-noise, low-drift, very high precision voltage references. These references are capable of both sinking and sourcing current, and have excellent line and load regulation.

Excellent temperature drift 3 ppm/°C and high accuracy 0.05% are achieved using proprietary design techniques. These features, combined with very low noise, make the REF50xx family ideal for use in high-precision data acquisition systems.

Each reference voltage is available in both high grade REF50xxIDGK and REF50xxID and standard grade REF50xxAIDGK and REF50xxAID. The reference voltages are offered in 8-pin VSSOP and SOIC packages, and are specified from –40°C to 125°C.
