Instrumentation amplifier is usedin the occasion whereneed to amplifier small level signalDC signal, andit is produced by minus skulls topology. Instrument amplifierhas the advantage of in-phase input's high impedance. This circuit is the basic instrument amplifier circuit, other instrumentation amplifiers areshown in the figure, here the input also use a single power supply. This circuit is actually a single power strain gauge. This circuit's fault is need completely equal resistance, otherwise this circuit's common mode rejection ratio will be very low.
