1) TUE is tested at
VAREFx = VDDPA, VAGND = 0 V. It is verified by design for all other voltages within the defined
voltage range.
The specified TUE is valid only if the absolute sum of input overload currents on Port 5 or Port 15 pins (see
I
OV specification) does not exceed 10 mA, and if VAREF and VAGND remain stable during the measurement time.
2)
V
AIN may exceed VAGND or VAREFx up to the absolute maximum ratings. However, the conversion result in these
cases will be X000H or X3FFH, respectively.
3) The limit values for
f
ADCI must not be exceeded when selecting the peripheral frequency and the prescaler
setting.
4) 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
tADCI depend on programming and are found in Table 19.
5) The total unadjusted error TUE is the maximum deviation from the ideal ADC transfer curve, not the sum of
individual errors.
All error specifications are based on measurement methods standardized by IEEE 1241.2000.
6) Not subject to production test - verified by design/characterization.
7) 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:
CAINTtyp = 12 pF, CAINStyp = 5 pF, RAINtyp = 1.0 k, CAREFTtyp = 15 pF, CAREFStyp = 10 pF, RAREFtyp = 1.0 k.
