A.2
This section describes the characteristics of the analog-to-digital converter.
A.2.1
The
The following constraints exist to obtain full-scale, full range results:
This constraint exists since the sample buffer amplifier can not drive beyond the power supply levels that
it ties to. If the input level goes outside of this range it will effectively be clipped.

A.2.2
Source resistance, source capacitance and current injection have an influence on the accuracy of the ATD.
A further factor is that PortAD pins that are configured as output drivers switching.

Num C
Full accuracy is not guaranteed when differential voltage is less than 4.50 V
When converting in Stop Mode (ICLKSTP=1) an ATD Stop Recovery time tATDSTPRCV is required to switch back to bus clock
based ATDCLK when leaving Stop Mode. Do not access ATD registers during this time.
The minimum time assumes a sample time of 4 ATD clock cycles. The maximum time assumes a sample time of 24 ATD clock
cycles and the discharge feature (SMP_DIS) enabled, which adds 2 ATD clock cycles.
