An inverting amplifier is a circuit involving the use of an amplifier, often an operational amplifier, which is configured such that the output is 180° out of phase with the input. That is, if a pos...

1. An inverting amplifier 2. A Non-inverting amplifier ... Opposite is a diagram of an INVERTING AMPLIFIER. This means that if the voltage going into the 741 chip is positive, it is negative when it comes out of the 741. In other words it reverses polarity (inverts polarity).

In such a case, one could either use the output of the inverting amplifier as the input to a second inverting amplifier which would cause the total gain to be positive. However, a simpler method would be to use the non-inverting amplifier configuration.

As we said at the top of this page, it is not generally a good idea to apply multiple input signals and resistors to the non-inverting amplifier. That doesn't mean it can't be done; there are some special-purpose circuits that use the interactions quite effectively.

A Java Applet provides practice in designing inverting amplifiers. ... When the op amp is not saturated, the inverting amplifier produces an output voltage, Vo, that is proportional to the input voltage, Vs. The output voltage is measured using a voltmeter. The input voltage is the voltage of the voltage source.

How does an opamp device simplify the design of an amplifier? The voltage gain for the inverting configuration is set by the ratio of the feedback resistors R1 and R2, not the internal gain of the opamp itself.
