(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 the number of LSBs or as a percent of the specified linear full-scale range FSR.
(2) Offset error drift is calculated using the box method as described by the following equation: AMC1305L25 AMC1305M05 AMC1305M25 ec_eodrift_bas654.gif
