(1) Steady-state voltage supported by the device in case of a system failure. See the specified common-mode input voltage V_CM for normal
operation. Observe analog input voltage range as specified in the Absolute Maximum Ratings table.
(2) This parameter is the –3-dB, second-order, roll-off frequency of the integrated differential input amplifier to consider for antialiasing filter
designs.
(3) 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 linear full-scale range FSR.
