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.
