This project on Inverting amplifier circuit demonstrates the principle of operation of opamp as inverting amplifier using 741. By this circuit we can amplify [[wysiwyg_imageupload::]]both AC and DC. If voltage is AC then its phase also changes; it gets inverted or is changed by 180 degree. Opamp is used to get high gains and can be used as amplifier in any circuit. It is due to prime importance in applicative and developmental areas that inverting configuration is a must for every electronic enthusiast and covering the basics of the inverting amplifier is this electronic circuit tutorial. IC 741 is used most of the time to play the role of the amplifier. This is a comparator IC and can be used in non-inverting configuration too depending upon how the power supply is connected. Keep on reading to find out how the circuit is constructed and what makes it work.

In this project about inverting amplifier, output voltage is fed back to input so as to cancel the effect of variation of temperature on voltage gain and improve [[wysiwyg_imageupload::]]stability of circuit with respect to temperature variations.Inverting inputs are more preferred than the non-inverting ones due to the main benefit of stability. Inverting amplifiers, hence, even though provide less gain, are used for more applications. From various electronic circuits such as integrator or differentiator, inverting amplifiers are used in designing filters for communication circuits.Without much change in the circuitry, inverting amplifiers can be made to work from AC to DC mode or vice versa. Hence, it becomes an easy task to design the circuits without giving much attention to the obvious power concerns. Let’s find out how to make an inverting circuit by using a transistor, a DC battery source and a few passive electronic components.
