Explain Various Operational Amplifier Circuits Used In Instrumentation. The op amps 1 2 are non inverting amplifiers and op amp 3 is a difference amplifier. This instrumentation amplifier provides high input impedance for exact measurement of input data from transducers.
Instrumentation amplifier s final output vout is the amplified difference of the input signals applied to the input terminals of op amp 3 let the outputs of op amp 1 and op amp 2 be vo1 and vo2 respectively. This instrumentation amplifier provides high input impedance for exact measurement of input data from transducers. In this circuit a non inverting amplifier is connected to each input of the differential amplifier.
This instrumentation amplifier provides high input impedance for exact measurement of input data from transducers.
I have used two lm358 ics. Three op amp instrumentation amplifier. The instrumentation amplifier using op amp circuit is shown below. Instrumentation amplifier s final output vout is the amplified difference of the input signals applied to the input terminals of op amp 3 let the outputs of op amp 1 and op amp 2 be vo1 and vo2 respectively.
