Op Amp Summing Amplifier. Fig 1 shows a three input summing amplifier. One of the important application of an operational amplifier is the summing amplifier or otherwise known as adder.
Fig 1 shows a three input summing amplifier. In this article we will see the summing amplifier circuit its working and its applications. In most of our previous tutorials concerning operational amplifiers only one input was applied to either the inverting or non inverting op amp s input.
In this article we will see the summing amplifier circuit its working and its applications.
The op amp inverting amplifier configuration lends itself to being used as a summing amplifier because of the fact that it has a virtual earth point. One of the simplest and basic applications of an operational amplifier is op amp as summing amplifier. The summing amplifier is another type of operational amplifier circuit configuration that is used to combine the voltages present on two or more inputs into a single output voltage. In most of our previous tutorials concerning operational amplifiers only one input was applied to either the inverting or non inverting op amp s input.
