must be connected for the 5 V ADC0 to operate properly.
The analog inputs of ADC0 are internally multiplied by a factor of 3.3 / 5. If V

3.3 V, the maximum digital result is 1024

Remark:
The following formula only applies to ADC0:
Voltage variations on VREFP (i.e. those that deviate from voltage variations on the
V
DDA(ADC5V5)
pin) are visible as variations in the measurement result.
Equation 1
shows
the formula used to determine the conversion result of an input voltage V
IN
on ADC0:
(1)
Remark:
Note that the ADC1 and ADC2 accept an input voltage up to of 3.6 V (see
Table 33
) on the ADC1/2 IN pins. If the ADC is not used, the pins are 5 V tolerant. The
ADC0 pins are 5 V tolerant.

Clock description
The ADC modules are clocked from two different sources; CLK_MSCSS_ADCx_APB and
CLK_ADCx (x = 0, 1, or 2), see
Section 6.6.2
. Note that each ADC has its own
CLK_ADCx and CLK_MSCSS_ADCx_APB branch clocks for power management. If an
ADC is unused both its CLK_MSCSS_ADCx_APB and CLK_ADCx can be switched off.
The frequency of all the CLK_MSCSS_ADCx_APB clocks is identical to
CLK_MSCSS_APB since they are derived from the same base clock
BASE_MSCSS_CLK. Likewise the frequency of all the CLK_ADCx clocks is identical
since they are derived from the same base clock BASE_ADC_CLK.
The register interface towards the system bus is clocked by CLK_MSCSS_ADCx_APB.
Control logic for the analog section of the ADC is clocked by CLK_ADCx, see also
Figure 9
.
