(1) The following voltages were applied to the SD24_B inputs:
V_I,A+(t) = 0 V + V_PP/2 × sin(2π × f_IN × t)
V_I,A-(t) = 0 V - V_PP/2 × sin(2π × f_IN × t)
resulting in a differential voltage of V_ID = V_I,A+(t) - V_I,A-(t) = V_PP × sin(2π × f_IN × t) with V_PP being selected as the maximum value allowed
for a given range (according to SD24_B recommended operating conditions).
