OPERATIONAL DESCRIPTION DEFINITION OF TERMS Differential Voltage It is the difference between two node voltages. For example, the output differential voltage (or equivalently output differential mode voltage) is defined − OUT, dm +OUT −OUT ...
Page 22
AD8132 THEORY OF OPERATION The AD8132 differs from conventional op amps by the external presence of an additional input and output. The additional input controls the output common-mode voltage. The OCM additional output is the analog complement of ...

AD8132 APPLICATIONS INFORMATION ANALOG-TO-DIGITAL DRIVER Many of the newer high speed ADCs are single supply and have differential inputs. Thus, the driver for these devices is able to convert from a single-ended signal to a differential signal and provide output ...
Page 27
SOURCE Any imbalance in the differential drive signal appears as a common-mode signal on the cable. This is the equivalent of a single wire that is driven with the common-mode signal. In this case, the wire acts as ...
