3) The limit values for

fBC must not be exceeded when selecting the peripheral frequency and the ADCTC setting.

4) This parameter includes the sample time

tS, the time for determining the digital result and the time to load the

result register with the conversion result (

tSYS = 1/fSYS).

Values for the basic clock

tBC depend on programming and can be taken from Table 15.

When the post-calibration is switched off, the conversion time is reduced by 12 x

tBC.

5) The actual duration of the reset calibration depends on the noise on the reference signal. Conversions

executed during the reset calibration increase the calibration time. The TUE for those conversions may be

increased.

6) 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 = 7 pF, RAINtyp = 1.5 kΩ, CAREFTtyp = 15 pF, CAREFStyp = 13 pF, RAREFtyp = 0.7 kΩ.
