7.3.2.1.2 Unipolar Analog Inputs
In addition to the bipolar input channels, the AMC7836 device includes five unipolar analog inputs. The analog input range for these channels is 0 V to 2 × Vref and the LSB size for these channels is 2 × Vref / 4096.
The unipolar analog input conversion values are stored in straight binary format in the ADC-Data registers (address 0x40 through 0x49). With the internal reference equal to 2.5 V, the input voltage is calculated by Equation 2.
Equation 2. 
In applications where the signal source has high impedance, externally buffering the unipolar analog input is recommended.
