The ADC noise exhibits characteristics of white noise with an amplitude spectral density of $5.6\,\mu V/\sqrt{\text{Hz}}$ (equivalent to $0.4\,\text{mV RMS}$), which satisfies the established specifications.
All ADC channels demonstrated similar performance, so only one channel's noise profile is shown.
If necessary, oversampling can be applied to further reduce the noise [[cite:&lab13_improv_adc]].
If necessary, oversampling can be applied to further reduce the noise cite:lab13_improv_adc.
To gain $w$ additional bits of resolution, the oversampling frequency $f_{os}$ should be set to $f_{os} = 4^w \cdot F_s$.
Given that the ADC can operate at 200kSPS while the real-time controller runs at 10kSPS, an oversampling factor of 16 can be employed to gain approximately two additional bits of resolution (reducing noise by a factor of 4).
This approach is effective because the noise approximates white noise and its amplitude exceeds 1 LSB (0.3 mV) [[cite:&hauser91_princ_overs_d_conver]].
