(1) Using IEEE Std 1241™-2010 for terminology and test methods.
(2) Input signal scaled down internally before conversion, as if voltage range was 0 to 4.3V
(3) No missing codes. Positive DNL typically varies from +0.3 to +3.5 depending on device, see Figure 5-13
(4) For a typical example, see Figure 5-14
