Inverting amplifier

Download for Macintosh or for PC.

This circuit inverts the polarity of the input voltage. The gain is given by -R1/R2, to a very close approximation.

In this simulation you can change the values of R1 and R2 in order to change the gain (click on the resistor value with the mouse pointer and edit like any text field), and you can can vary the slider on the left to change the input voltage. As before, if you attempt to make the output voltage exceed the output voltage limits (+14 and -14 volts), the output will "saturate" at the limit until the input voltage is reduced. The gain equation is valid only if the amplifier is not saturated.
