(1)
The leakage current is defined in the leakage current table with Px.x/Ax parameter.
(2)
The analog input voltage range must be within the selected reference voltage range VR+ to VR– for valid conversion results.
(3)
The internal reference supply current is not included in current consumption parameter IADC10.
(4)
The internal reference current is supplied via terminal VCC. Consumption is independent of the ADC10ON control bit, unless a
conversion is active. The REFON bit enables the built-in reference to settle before starting an A/D conversion.
