_______________________________________________________________________________________
Note 1:
Contact factory for INL limits applicable with FS1 = 0 and MF1, MF0 = 1, 2, or 3.
Note 2:
To achieve optimum INL performance with the MAX1401, ensure that the PCB layout carefully shields the MUXOUT and
ADCIN pins from any digital noise source. The MAX1401’s INL is production tested with 150pF connected between
MUXOUT+ and MUXOUT- to minimize the effect of differential coupling from the CLKIN and CLKOUT pins.
Note 3:
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 4:
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 5:
Full-Scale Drift includes zero-scale drift (unipolar offset drift or bipolar zero drift) and applies to both unipolar and bipolar
input ranges.
Note 6:
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 7:
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 8:
Use of the offset DAC does not imply that any input may be taken below AGND.
Note 9:
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 10: Guaranteed by design or characterization; not production tested.
Note 11: The input voltage must be within the Absolute Input Voltage Range specification.
Note 12: All AIN and REFIN pins have identical input structures. Leakage is production tested only for the AIN3, AIN4, AIN5,
CALGAIN, and CALOFF inputs.
Note 13: The dynamic load presented by the MAX1401 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 that this value does not
include any additional capacitance added by the user to the MUXOUT_ or ADCIN_ pins.
Note 14: 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 15: VREF = VREFIN+ - VREFIN-.
