Figure 61. Circuit Definitions
Differential Voltage
Differential voltage refers to the difference between two node
voltages. For example, the differential output voltage (or
equivalently, output differential mode voltage) is defined as
VOUT, dm = (V+OUT VOUT)
where V+OUT and VOUT refer to the voltages at the +OUT and
OUT terminals with respect to a common reference.
Similarly, the differential input voltage is defined as
VIN, dm = (+DIN (DIN))
Common-Mode Voltage (CMV)
CMV refers to the average of two node voltages. The output
common-mode voltage is defined as
VOUT, cm = (V+OUT + VOUT)/2
Similarly, the input common-mode voltage is defined as
VIN, cm = (+DIN + (DIN))/2
Common-Mode Offset Voltage
The common-mode offset voltage is defined as the difference
between the voltage applied to the VOCM terminal and the
common mode of the output voltage.
VOS, cm = VOUT, cm VOCM
Differential VOS, Differential CMRR, and VOCM CMRR
The differential mode and common-mode voltages each have
their own error sources. The differential offset (VOS, dm) is the
voltage error between the +IN and IN terminals of the amplifier.
Differential CMRR reflects the change of VOS,dm in response to
changes to the common-mode voltage at the input terminals
+DIN and DIN.

Balance
Balance is a measure of how well the differential signals are
matched in amplitude; the differential signals are exactly 180°
apart in phase. By this definition, the output balance is the
magnitude of the output common-mode voltage divided by
the magnitude of the output differential mode voltage.
