Differential Inputs
The ADC can be used either as a single ended ADC (DIFF bit equal to 0) or as a fully differential
ADC (DIFF bit equal to 1) as shown in
ended mode.
If ANACH is set in ADC_MR the ADC can apply a different mode on each channel. Otherwise
the parameters of CH0 are applied to all channels.
The same inputs are used in single ended or differential mode.
In single ended mode, inputs are managed by a 16:1 channels analog multiplexer. In the fully
differential mode, inputs are managed by an 8:1 channels analog multiplexer. See
and
Table 38-4.
