Note 1:
2:
3:
The ADC conversion result never decreases with an increase in the input voltage and has no missing codes.
Measurements taken with external VREF+ and VREF- are used as the ADC voltage reference.
External reference voltage applied to VREF+/- pins. IVREF is current during conversion at 3.3V, 25°C.
Parameter is for design guidance only and is not tested.
4: Impedance during sampling is at 3.3V, 25°C. Parameter is for design guidance only and is not tested.
