The REF50xx is a family of low-noise, low-drift, very high precision voltage references.

These references are capable of both sinking and sourcing, and they are very robust with regard to line and load changes.
Excellent temperature drift (3ppm/°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 standard- and high-grade versions. They are offered in MSOP-8 and SO-8 packages and specified from –40°C to +125°C.
The REF50xx family of voltage references features extremely low dropout voltage. These references can be operated with a supply of 200mV above the output voltage in an unloaded condition. The REF50xx provides a very accurate, factory-trimmed voltage output. However, VOUT can be adjusted using the trim and noise reduction pin (TRIM/NR, pin 5). The REF50xx allows access to the bandgap through the TRIM/NR pin.
REF5050 may be used for model output voltage, data acquisition systems, ATE equipment, industrial process control, medical instrumentation, optical control systems, and precision instrumentation.
