(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 analog input voltage range as specified in the Absolute Maximum Ratings table.
(2) This parameter is the –3dB, 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.
(4) Offset error drift is calculated using the box method as described by the following equation: AMC1303E0510 AMC1303M0510 AMC1303E0520 AMC1303M0520 AMC1303E2510 AMC1303M2510 AMC1303E2520 AMC1303M2520 .
