Table 67-37. ADC Analog Input Characteristics
Symbol	Parameter	Conditions	Min	Typ	Max	Unit
V_FS	Analog Input Full Scale Range⁽¹⁾	ADC_COR.DIFFx = 0	0	–	V_ADVREF	V
V_FS	Analog Input Full Scale Range⁽¹⁾	ADC_COR.DIFFx = 1	-V_ADVREF	–	V_ADVREF	V
V_INCM	Common Mode input range⁽²⁾	ADC_COR.DIFFx = 1	0.4 × V_DDANA	–	0.6 × V_DDANA	V
C_IN	ADC sampling capacitance	–	–	–	3	pF
C_{P_ADx}	Analog input parasitic capacitance⁽⁴⁾	ADx pin configured as analog input	–	–	10	pF
Z_IN	Common Mode Input impedance⁽³⁾	On ADx pin	1 / (f_S × C_{P_ADx})	–	–	Ω

Note:

V_FS = V_ADx in Single-ended mode, V_FS = (V_ADx - V_ADx+1) in Differential mode.
V_INCM = (V_ADx + V_ADx+1) / 2.
See the figure "Input Channel Model". When converting one single channel, most of the input parasitic capacitance in not switched, therefore the common mode input impedance reduces to Z_IN = 1 / (f_S × C_IN).
Includes C_IN.
