Digital A/D conversion result
The conversion is monotonic, meaning that the result never decreases if the analog input
does not and never increases if the analog input does not.
If the input voltage (VAIN) is greater than VDDA (high-level voltage reference) then the
conversion result is FFh in the ADCDRH register and 03h in the ADCDRL register (without
overflow indication).
If the input voltage (VAIN) is lower than VSSA (low-level voltage reference) then the
conversion result in the ADCDRH and ADCDRL registers is 00 00h.
The A/D converter is linear and the digital result of the conversion is stored in the ADCDRH
and ADCDRL registers. The accuracy of the conversion is described in the Electrical
Characteristics Section.
RAIN is the maximum recommended impedance for an analog input signal. If the impedance
is too high, this will result in a loss of accuracy due to leakage and sampling not being
completed in the alloted time.
A/D conversion phases
The A/D conversion is based on two conversion phases:
●
Sample capacitor loading [duration: tSAMPLE]
During this phase, the VAIN input voltage to be measured is loaded into the CADC
sample capacitor.
●
A/D conversion [duration: tHOLD]
During this phase, the A/D conversion is computed (8 successive approximations
