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

ADCI depend on programming.

3) The broken wire detection delay against

AGND is measured in numbers of consecutive precharge cycles at a

conversion rate of not more than 500 µs. Result below 10% (66

4) The broken wire detection delay against

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

AIN may exceed VAGND or VAREF up to the absolute maximum ratings. However, the conversion result in these

cases will be X000

H or X3FFH, respectively.
