4.4.5 Auxiliary Fast Analog Inputs
The fast analog inputs feature an ADC with 16bit resolution and a build-in 2nd-order low pass
filter. All inputs are galvanically isolated to the internal ground of the controller. The correspond-
ing GND signals of the specific inputs should be used to archive the best performance. The input
range of the analog inputs is configurable for unipolar as well as bipolar operation. Note that this
setting is global for all analog inputs. The total number of six analog inputs are mapped in groups
of two to the channels of the corresponding driver module.
