(1) Integral nonlinearity is defined as the maximum deviation from a straight line passing through the end-points of the ideal ADC transfer function expressed as number of LSBs or as a percent of the specified 500-mV input range.
(2) Maximum values, including temperature drift, are ensured over the full specified temperature range.
(3) Ensured by design.
