38.5.11 ADC Timings

The ADC start-up time is programmed using ADC_MR.STARTUP. 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 ensure 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 by using ADC_MR.TRACKTIM and ADC_EMR.TRACKX.

Warning: No input buffer amplifier to isolate the source is included in the ADC. Refer to the section “Electrical Characteristics”.
