50 k Can go higher if external 0.01F capacitor is

present on input pin.

† Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are not

tested.

Note 1: Total Absolute Error includes integral, differential, offset and gain errors.

2: The A/D conversion result never decreases with an increase in the input voltage and has no missing codes.

3: When ADC is off, it will not consume any current other than leakage current. The power-down current specification

includes any such leakage from the ADC module.
