Notes: 9. The minimum Full Scale Calibration Range (FSCR) is limited by the maximum allowed gain register
value (with margin). The maximum FSCR is limited by the ∆Σ modulator’s 1’s density range.
10. The maximum full scale signal can be limited by saturation of circuitry within the internal signal path.
11. All outputs unloaded. All input CMOS levels.
