(1)
The leakage current is defined in the leakage current table with P6.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 IADC12.
(4)
The internal reference current is supplied via terminal AVCC. Consumption is independent of the ADC12ON control bit, unless a
conversion is active. The REFON bit enables settling of the built-in reference before starting an A/D conversion.
(5)
Not production tested, limits verified by design.

(1)
The external reference is used during conversion to charge and discharge the capacitance array. The input capacitance, CI, is also the
dynamic load for an external reference during conversion. The dynamic impedance of the reference supply should follow the
recommendations on analog-source impedance to allow the charge to settle for 12-bit accuracy.
(2)
The accuracy limits the minimum positive external reference voltage. Lower reference voltage levels may be applied with reduced
accuracy requirements.
(3)
The accuracy limits the maximum negative external reference voltage. Higher reference voltage levels may be applied with reduced
accuracy requirements.
(4)
The accuracy limits minimum external differential reference voltage. Lower differential reference voltage levels may be applied with
reduced accuracy requirements.
