9.4.6.11 ADC Timings

The ADC start-up time is programmed through the ADC_MR.STARTUP field. Refer to the section “Electrical Characteristics”.

The ADC Controller provides an inherent tracking time of six ADC clock cycles.

A minimal tracking time is necessary for the ADC to guarantee the best converted final value between two conversions. The tracking time can be adjusted to accommodate a range of source impedances. If more than six ADC clock cycles are required, the tracking time can be increased using the ADC_MR.TRACKTIM field and ADC_EMR.TRACKX4.
