Hallo, laut Datenblatt kann ich noch eine Verstärkung? Einstellen? Was genau bewirkt das verstellen von den Gain Bits? Laut Datenblatt: Analog front end Analog channel inputs of voltages VIP1, VIN1, VIP2, VIN2 and currents IIP1, IIN1; IIP2, IIN2 are fully differential. Voltage channels have a preamplification gain of 2, which defines the maximum differential voltage on voltage channel inputs to ± 300 mV. Current channels have a programmable gain selectable among 2, 4, 8 and 16, which defines the maximum differential voltage on current channel to ±300 mV, 150 mV, 75 mV or ±37.5 mV respectively. The selection is given by GAINx[1:0] (DFE_CR1, DFE_CR2) bits as described in the following table
