Specifications

5.26.7 Precision ADC

Table 5-27 lists the power supply and input range conditions for the ADC.

(1)

The analog input voltage range must be within the selected reference voltage range VR+ to VR– for valid conversion results.

(2)

The internal reference supply current is not included in current consumption parameter I(ADC14).

(3)

Represents only the ADC switching capacitance. See the digital inputs electrical specification for internal parasitic pin capacitance.
