Note 1:
Contact factory for INL limits applicable with FS1 = 0 and MF1, MF0 = 1, 2, or 3.
Note 2:
Nominal gain is 0.98. This ensures a full-scale input voltage may be applied to the part under all conditions without caus-
ing saturation of the digital output data.
Note 3:
Positive Full-Scale Error includes zero-scale errors (unipolar offset error or bipolar zero error) and applies to both unipolar
and bipolar input ranges. This error does not include the nominal gain of 0.98.
Note 4:
Full-Scale Drift includes zero-scale drift (unipolar offset drift or bipolar zero drift) and applies to both unipolar and bipolar
input ranges.
Note 5:
Gain Error does not include zero-scale errors. It is calculated as (full-scale error - unipolar offset error) for unipolar ranges
and as (full-scale error - bipolar zero error) for bipolar ranges. This error does not include the nominal gain of 0.98.
Note 6:
Gain-Error Drift does not include unipolar offset drift or bipolar zero drift. It is effectively the drift of the part if zero-scale
error is removed.
Note 7:
Use of the offset DAC does not imply that any input may be taken below AGND.
Note 8:
Additional noise added by the offset DAC is dependent on the filter cutoff, gain, and DAC setting. No noise is added for a
DAC code of 0000.
Note 9:
Guaranteed by design or characterization; not production tested.
Note 10: The absolute input voltage must be within the input voltage range specification.
Note 11: All AIN and REFIN pins have identical input structures. Leakage is production tested only for the AIN3, AIN4, AIN5,
CALGAIN, and CALOFF inputs.
Note 12: The dynamic load presented by the MAX1403 analog inputs for each gain setting is discussed in detail in the Switching
Network section. Values are provided for the maximum allowable external series resistance.
Note 13: The input voltage range for the analog inputs is with respect to the voltage on the negative input of its respective differen-
tial or pseudo-differential pair. Table 5 shows which inputs form differential pairs.
Note 14: VREF = VREFIN+ - VREFIN-.
Note 15: These specifications apply to CLKOUT only when driving a single CMOS load.
