Note 12: Programming time does not include overhead associated with the utility ROM interface.
Note 13: V
Note 14: The operational input voltage range for each individual input of a differentially configured pair is from GND to AVDD. The
Note 15: The typical value is applied when a conversion is requested with ADPMO = 0. Under these conditions, the minimum delay
Note 16: Switching ADC reference from either internal or external reference to AVDD. Sample accuracy is not guaranteed prior to
Note 17: Total on-board decoupling capacitance on the AVDD pin < 100nF. The output impedance of the regulator driving the
Note 18: This parameter is guaranteed by design and is not production tested.
