Figure 96. Voltage Follower Circuit
Voltage gain is 0dB.
Using this circuit, the output voltage (OUT) is
configured to be equal to the input voltage (IN). This
circuit also stabilizes the output voltage (OUT) due to
high input impedance and low output impedance.
Computation for output voltage (OUT) is shown below.

OUT
For inverting amplifier, input voltage (IN) is amplified
by a voltage gain and depends on the ratio of R1 and
R2. The out-of-phase output voltage is shown in the
next expression
OUT=-(R2/R1)IN
This circuit has input impedance equal to R1.

OUT
For non-inverting amplifier, input voltage (IN) is
amplified by a voltage gain, which depends on the ratio
of R1 and R2. The output voltage (OUT) is in-phase
with the input voltage (IN) and is shown in the next
expression.
OUT=(1 + R2/R1)IN
Effectively, this circuit has high input impedance since
its input side is the same as that of the operational
amplifier.
