SPC56 ADC precision or standard channels

Hello,

Can anybody explain me the exact difference between the ADC precision channels and the ADC standard channels for a SPC560B?

I read the ADC section within the reference manual, but I did not find any differences.

Best regards,

Patrik

Hello Patrik,

the precision channels are internally multiplexed and have a better accuracy.

Comparing the standards one, the precision channels are mapped on input only I/O cells.

(cf Functional Port Pin description)

The implicit channel conversion priority in the case in which all channels are selected is the

following: Precision[0:x], Standard[0:y], External[0:z].

    Best regards
