Bipolar Input Operation
The circuit in Figure 10a can be used for bipolar input
operation. The input voltage is scaled by an amplifier
so that only positive voltages appear at the ADC’s
inputs. The analog input range is ±4V and the output
code is complementary offset binary. The ideal
input/output characteristic is shown in Figure 10b.
