(1) The following voltages are applied to the SD24 inputs:
VI,A+(t) = 0 V + VPP/2 × sin(2π × fIN × t)
VI,A–(t) = 0 V – VPP/2 × sin(2π × fIN × t)
resulting in a differential voltage of VID = VIN,A+(t) – VIN,A–(t) = VPP × sin(2π × fIN × t) with VPP being selected as the maximum value allowed for a given range (according to SD24 input range).
