As shown above, when −D
feedback of +OUT to −IN via the internal feedback resistor.
This contrasts with the typical gain of 2 operation where −D
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 +D
are referenced to ground. The ground voltage at V
reference for this circuit. In this unity gain configuration, if a dc
voltage is applied to V
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 +D
