Note 2: These specifications are not fully tested and are guaranteed by design and/or characterization.
Note 3: VAINP = VAINN.
Note 4: ppmFSR is parts per million of full-scale range.
Note 5: Positive full-scale error includes zero-scale errors.
Note 6: The MAX11201A has no normal-mode rejection at 50Hz or 60Hz.
