5 Noise Level Comparison With ADC Reference 5V/3.3V

Here, the Data Visualizer graph of a DC noisy signal is plotted with both 3.3V and 5V ADC reference and the noise level is compared with a given input DC signal VDD/2.

As ADC is configured with reference VDD, by changing the jumper on HPC board the ADC reference voltage can be changed.

Input signal from Signal & Noise Generator board: DC VDD/2 + random noise 0.5V peak-to-peak.

The ADC² computation mode is selected as the Average mode.
