The below code is used to observe the effect of changing one of the IADC parameters, in this case, the OSR value. The voltages are set as per Figure 2-2, and the IADC output is measured 100 times. Figure 2-4 shows the impact on the measured values in time domain, while Figure 2-5 shows the same in a histogram.
