1) These parameter values cover the complete operating range. Under relaxed operating conditions
(temperature, supply voltage) typical values can be used for calculation. At room temperature and nominal
supply voltage the following typical values can be used: C_AINTtyp = 12 pF, C_AINStyp = 5 pF, R_AINtyp = 1.0 kOhm,
C_AREFTtyp = 15 pF, C_AREFStyp = 10 pF, R_AREFtyp = 1.0 kOhm.
2) This parameter includes the sample time (also the additional sample time specified by STC), the time to
determine the digital result and the time to load the result register with the conversion result. Values for the
basic clock t_ADCI depend on programming.
3) The broken wire detection delay against V_AGND is measured in numbers of consecutive precharge cycles at a
conversion rate of not more than 500 μs. Result below 10% (66_H)
