OPERATIONAL DESCRIPTION
DEFINITION OF TERMS
Rev. PrD | Page 9 of 14
Figure 4. Circuit Definitions
Differential Voltage
This refers to the difference between two node voltages. For
example, the output differential voltage (or equivalently, output
differential-mode voltage) is defined as
V
OUT, dm
= (
V
+OUT
V
OUT
)
where
V
+OUT
and
V
OUT
refer to the voltages at the +OUT and
OUT terminals with respect to a common reference.
Common-Mode Voltage
This refers to the average of two node voltages. The output
common-mode voltage is defined as
V
OUT, cm
= (
V
+OUT
+
V
OUT
)/2
Balance
Balance is a measure of how well differential signals are
matched in amplitude and are exactly 180° 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.
