Data in “Typ” column is at 5V, 25°C unless otherwise stated. These parameters are for design guidance only and are
not tested.
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.
V
The A/D conversion result never decreases with an increase in the input voltage and has no missing codes.
Maximum allowed impedance for analog voltage source is 10 k
