* These parameters are characterized but not tested.
â Data in âTypâ column is at 5V, 25°C unless otherwise stated. These parameters are for design guidance only and are
not tested.
Note 1: When A/D is off, it will not consume any current other than minor leakage current. The power-down current spec
includes any such leakage from the A/D module.
2: VREF current is from RA3 pin or VDD pin, whichever is selected as reference input.
3: The A/D conversion result never decreases with an increase in the input voltage and has no missing codes.
4: Maximum allowed impedance for analog voltage source is 10 kïï®ï This requires higher acquisition time.
