1. Specifications are based on 20 minutes warm-up, self-calibration temperature at 23 °C, and bipolar input range of ± 10 V.
2. The measurements are calculated with 100 points averaging of data.
3. The noise rms value is the standard deviation of 20000 points.
4. The crosstalk measurements are tested up to input frequency of Fin = MaxSamplingRate/2.
