Op-amp as subtractor | op-amp difference amplifier | LICA | ushendra's engineering tutorials

#opampsubtractor #differenceamplifier #opamp One of a very important practical application of operational amplifier is an 'INSTRUMENTATION AMPLIFIER ' used to amplify the low level output signals from transducers. This instrumentation amplifier., it's construction, working principle is based on a op-amp subtractor also known by the name difference amplifier, where in the output is the difference of the two inputs. the beginner should have an idea on op-amp subtractor to understand the function of instrumentation amplifier. The working of a op-amp based subtractor is explained in this lecture video by 'ushendra's engineering tutorials' with a mathematical approach. The required equation is derived very transparently so that it can be easily understood by a beginner even.
