UNITY-GAIN, SINGLE-ENDED-TO-DIFFERENTIAL
DRIVER
If it is not necessary to offset the output common-mode voltage
(via the VOCM pin), then the AD8131 can make a simple unity-
gain single-ended-to-differential amplifier that does not require
any external components. Figure 43 shows the schematic for
this circuit.

Figure 43. Unity Gain, Single-Ended-to-Differential Amplifier
As shown above, when DIN is left floating, there is 100%
feedback of +OUT to IN via the internal feedback resistor.
This contrasts with the typical gain of 2 operation where DIN is
grounded and one third of the +OUT is fed back to IN. The
result is a closed-loop differential gain of 1.
Upon careful observation, it can be seen that only +DIN and VOCM
are referenced to ground. The ground voltage at VOCM is the
reference for this circuit. In this unity gain configuration, if a dc
voltage is applied to VOCM to shift the common-mode voltage, a
differential dc voltage will be created at the output, along with the
common-mode voltage change. Thus, this configuration cannot
be used when it is desired to offset the common-mode voltage of
the output with respect to the input at +DIN.
