Tested on both 2.55V full scale and -1.28V to 1.27V full scale.
Minimum resolution for which there are no missing codes.
Parameter is tested at VCC = +5V, but is guaranteed from VCC = 4.5V to VCC = 5.5V
The absolute input signal range defines the limits of input signal value from either the (+) or (-) input to ground (as a function of VCC) over which
the device will produce distinct output codes.
5/
The differential input signal range defines the input signal span over which distinct output codes are produced. As this range is exceeded, the
device ceases to change output state (see fig. 4).
6/

Guaranteed, if not tested, to the specified limits.
255 mV range. CMRR tested with 0V and full scale applied to analog inputs output change measured from 0 to VCM maximum and 0 to VCM
minimum and will not exceed specified limits.
