What is Inverting Operational Amplifier?
An Inverting operational Amplifier is a device used in electronics engineering for amplifying the output and generating an output voltage that has a phase opposite to the input waveform. It is usually built using an operational amplifier and some resistors. Let us see the formal definition of
The inverting operational amplifier can be described as an amplifier with fixed-gain which produces a negative output voltage as its gain is always negative.
We can say that the output of inverting operational amplifier is out of phase with respect to its input by 1800. This can be interpreted that for a negative input pulse, the output will be positive and for a positive input pulse, the output wave will be negative.
Inverting Operational Amplifier
Operational amplifiers are an important category of instruments used in electronics engineering. Often they are used for the task of amplifying the output. In this category of instruments, there is a subcategory known as Inverting Operational Amplifiers. They are typically used when we need an opposite phase for the input waveform. In this article, we will discuss what is Inverting Operational Amplifier. We will discuss their work and the equation used for calculating the gain of an Inverting Operational Amplifier. We will also discuss the advantages and disadvantages of Inverting Operational Amplifier. To understand the real-life usage of these, we will also discuss some applications of Inverting Operational Amplifiers. The article will also aim to provide a comparative analysis between an Inverting operational Amplifier and a Non-Inverting Operational Amplifier. We will conclude the article with some frequently asked questions.
