52       Some ADCs have differential input pins that can be used to measure
53       single-ended or pseudo-differential inputs. This property can be used
54       in addition to single-channel to signal software that this channel is
55       not differential but still specify two inputs.
57       The input pair is specified by setting single-channel to the positive
58       input pin and common-mode-channel to the negative pin.
