LSb VINL = AVSS = VREFL = 0V,
AVDD = VREFH = 5V
LSb VINL = AVSS = VREFL = 0V,
AVDD = VREFH = 5V
LSb VINL = AVSS = VREFL = 0V,
AVDD = VREFH = 5V
LSb VINL = AVSS = VREFL = 0V,
AVDD = VREFH = 5V
— Guaranteed
Note 1: The ADC conversion result never decreases with an increase in the input voltage.
2: Measurements are taken with external VREF+ and VREF- used as the ADC voltage reference.
