Time Domain Analysis
The plot begins when the START button in pressed. When the chart begins to display data, the START
button changes to STOP. Data are displayed on the chart until the STOP button is pressed. There are two
ways the data can be displayed. One option is to display by voltage and the second option displays by the
number of codes. The voltage option is the default, and the voltage value displayed depends on the gain
applied in the register setting and the reference voltage being used. The default reference voltage
displayed is the internal reference voltage of the ADS1119. If another reference source is used, update
the reference voltage box to accurately display the voltage value determined at the ADC input.
Additional information is also displayed above the chart in terms of ADC conversion codes. This
information includes the number of samples, mean value, standard deviation, peak-to-peak, effective
resolution and noise-free bits of the data set collected.
