4.2.5 Histogram Display

Noise degrades ADC resolution and the histogram tool shown in Figure 4-11 can be used to estimate effective resolution. Effective resolution is a metric describing the ADC resolution loss resulting from noise generated by the various sources connected to the ADC when measuring a dc signal. The cumulative effect of noise coupling to the ADC output from sources such as the input drive circuits, the reference drive circuit, the ADC power supply, and the ADC 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.
