2.1.4 ADC Input Noise

ADC input noise refers to the noise that is superimposed on the original signal during the process of collecting, amplifying, and transmission to the ADC analog input terminal. The input noise can be measured by an oscilloscope. Due to the numerous links involved in signal input, it is easy to receive various interferences. In the design of input links, reasonable layout and wiring, as well as the addition of RC filtering, can be used to minimize the interference on the input signal and filter out high-frequency noise as much as possible.
