Conditions

Note 1:

Because the sample caps will eventually lose charge, clock rates below 10 kHz can affect linearity

performance, especially at elevated temperatures.

The A/D conversion result never decreases with an increase in the input voltage, and has no missing

codes.

Measurements were taken with external VREF+ and VREF- used as the ADC voltage references.
