(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 4.3 V. Applied voltage must be within the absolute
maximum ratings (see Section 5.1) at all times.
(3) No missing codes. Positive DNL typically varies from 0.3 to 1.7, depending on the device (see Figure 5-7).
(4) For a typical example, see Figure 5-6.
