ANALOG CHARACTERISTICS (Continued)
Notes: 7. See the section of the data sheet which discusses Analog Input Models.
8. 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. See
“Analog Input” section for details. Also see “Limitations in Calibration Range”.
9. VREF must be less than or equal to supply voltages.
10. All outputs unloaded. All inputs CMOS levels. Power consumption scales linearly with changes in
supply voltage.
