6.4 Histogram Tool

Noise degrades ADC resolution and the histogram tool can be used to estimate effective resolution, which is an indicator of the number of bits of ADC resolution losses 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.

The histogram corresponding to a dc input is displayed on clicking on the Capture button, as shown in Figure 6-7:
