4. This parameter is fixed by ADC control logic.
5. DNL, INL, TUE are tested at V
voltages within the defined voltage range.
‘LSB’ has a value of V
The specified TUE is guaranteed only if an overload condition (see I
pins and the absolute sum of input overload currents on all analog input pins does not exceed 10mA.
6. The coupling factor is measured on a channel while an overload condition occurs on the adjacent not selected channel with an
absolute overload current less than 10mA.
7. Partially tested, guaranteed by design characterization.
8.To remove noise and undesirable high frequency components from the analog input signal, a low-pass filter must be connected at
the ADC input. The cut-off frequency of this filter should avoid 2 opposite transitions during the t
