Note 1: Because the sample caps will eventually lose charge, clock rates below 10 kHz can affect linearity
performance, especially at elevated temperatures.
2: The A/D conversion result never decreases with an increase in the input voltage and has no missing codes.
3: Measurements taken with external V
REF+ and VREF- used as the ADC voltage references.
