INVERTING AMPLIFIER APPLICATION
The inverting amplifier configuration may be used instead of the more common non-inverting amplifier
configuration shown in
configuration shown in
. The inverting amplifier can have better THD+N performance and eliminates the
need for a large capacitor (Ci) reducing cost and space requirements. The values show in
are only one
example of an amplifier with a gain of 20V/V (Gain = -R
f
/R
i
). For different resistor values, the value of R
B
should
be eqaul to the parallel combination of R
f
and Ri.
