4.1.5 Histogram Analysis Display
Noise degrades ADC resolution and the histogram tool can be used to estimate effective resolution. The
cumulative effect of noise coupled to the ADC output comes from sources such as the input drive circuits,
reference drive circuit, ADC power supply, and the ADC. Cumulative noise is reflected in the standard deviation
of the ADC output code histogram that is obtained by performing multiple conversions of a DC input applied to
a given channel. Figure 4-9
