Electrical Parameters
4) This parameter includes the sample time (also the additional sample time specified by STC), the time for
determining the digital result and the time to load the result register with the conversion result.
Values for the basic clock tADCI depend on programming and can be taken from Table 16.
5) Not subject to production test - verified by design/characterization.
The given parameter values cover the complete operating range. Under relaxed operating conditions
(temperature, supply voltage) reduced values can be used for calculations. At room temperature and nominal
supply voltage the following typical values can be used:
CAINTtyp = 12 pF, CAINStyp = 5 pF, RAINtyp = 1.0 kΩ, CAREFTtyp = 15 pF, CAREFStyp = 10 pF, RAREFtyp = 1.0 kΩ.
