1) These parameter values cover the complete operating range. Under relaxed operating conditions (room
temperature, nominal supply voltage) the typical values can be used for calculation.
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).
4) The broken wire detection delay against V_AREF is measured in numbers of consecutive precharge cycles at a
conversion rate of not more than 10 µs. This function is influenced by leakage current, in particular at high
temperature. Result above 80% (332_H).
5) TUE is tested at V_AREF = V_DDPA = 5.0 V, V_AGND = 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 analog
port pins (see I_OV specification) does not exceed 10 mA, and if V_AREF and V_AGND remain stable during the
measurement time.
6) V_AIN may exceed V_AGND or V_AREF up to the absolute maximum ratings. However, the conversion result in these
cases will be X000_H or X3FF_H, respectively.
