H A Dad7380.rst80 This family supports 2 types of oversampling: normal average and rolling
83 available: 1 (oversampling disabled)/2/4/8/16/32.
85 When the on-chip oversampling function is enabled the performance of the ADC can
88 resolution boost feature can only be enabled when oversampling is enabled and
89 oversampling is not as useful without the resolution boost, the driver
90 automatically enables the resolution boost if and only if oversampling is
96 libiio does not support it. So when enabling or disabling oversampling, user
