OPERATIONAL DESCRIPTION
Differential voltage refers to the difference between two node
voltages. For example, the output differential voltage (or
equivalently output differential-mode voltage) shown in

Common-mode voltage refers to the average of two node
voltages. The output common-mode voltage is defined as
Balance is a measure of how well differential signals are
matched in amplitude and exactly 180 degrees apart in phase.
Balance is most easily determined by placing a well-matched
resistor divider between the differential voltage nodes and
comparing the magnitude of the signal at the divider’s midpoint
with the magnitude of the differential signal. By this definition,
output balance is the magnitude of the output common-mode
voltage divided by the magnitude of the output differential-
mode voltage.
