Note 1: These parameters are not characterized or tested in manufacturing.
2: These parameters are characterized, but not tested in manufacturing.
3: Characterized with a 1 kHz sine wave.
4: The ADC module is functional at V
BORMIN < VDD < VDDMIN, but with degraded performance. Unless
otherwise stated, module functionality is guaranteed, but not characterized.
