... The offset voltage from the light pen can be positive or negative. In general, the offset between any two channels is smaller than the absolute offsets. As negative input signals cannot be handled by the TZA1038HW internal servo channels, a two-step approach is adopted: A coarse DAC, common to all the input channels, adds an offset that shifts the input signals in positive direction until all inputs are 0 ...
