(1) Steady-state voltage supported by the device in case of a system failure. See the specified common-mode input voltage VCM for normal operation. Observe the analog input voltage range as specified in the Absolute Maximum Ratings table.
(2) The common-mode overvoltage detection level has a typical hysteresis of 90 mV.
(3) This parameter is the –3-dB, second-order, roll-off frequency of the integrated differential input amplifier to consider for antialiasing filter designs.
(4) 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 a number of LSBs or as a percent of the specified linear full-scale range (FSR).
(5) Offset error drift is calculated using the box method, as described by the following equation:
