1.4 Analog Output (OUT)
The analog output is internally buffered and capable
of driving capacitive loads ranging up to 50nF.

pin.
Additional circuitry to protect A/D converter input
against excessive voltage is not required.
Hereafter follow some definitions (see Figure 10
and following).
The analog output is also defined by some dynamic
characteristics (see figure 8):
