may exceed
V

or

AREF
up to the absolute maximum ratings. However, the conversion result in these
cases will be X000
H
or X3FF
H
, respectively.
3) The limit values for
f
BC
must not be exceeded when selecting the peripheral frequency and the ADCTC setting.
4) This parameter includes the sample time
t
S
, the time for determining the digital result and the time to load the
result register with the conversion result (
t
SYS
= 1/
f
SYS
).
Values for the basic clock
t
BC
depend on programming and can be taken from
Table 4-7
.
When the post-calibration is switched off, the conversion time is reduced by 12 x
t
BC
.
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:
