1. dB units referred to the typical full-scale voltage.
2. These full-scale values were measured with R
3. The full-scale voltage can be changed be scaling R
4. Measured between AIN_xx+ and AN_xx-.
5. Measured between AIN_xx+ and AGND.
6. Decreasing Full-Scale voltage by reducing R
7. Common mode input current should be kept to less than +/- 160uA to avoid performance degradation: |(I
8. This number was measured using perfectly matched external resistors (R
