LHR3025AFMA

The LHR30xx is a family of low noise, low drift, very high precision voltage references. These references support both sinking and sourcing current and have excellent line and load regulation. Excellent temperature drift (3ppm/°C) and high accuracy (0.05%) are achieved using proprietary design techniques. These features, combined with extremely low noise, make the LHR30xx family ideal for high precision data acquisition systems. Each reference voltage has a high grade and a standard grade. The reference voltage is available in 8-pin SOP8L and MSOP8L packages and is specified over the –40°C to 125°C temperature range.
