Design of an Instrumentation Amplifier
www.egr.msu.eduInstrumentation amplifiers are used in many different circuit applications. Their ability to reduce noise and have a high open loop gain make them important to circuit design. Figures 1-3 illustrate several different applications that utilize instrumentation amplifiers. The instrumentation amplifiers shown in figures 1-3 are the INA128.
A Designer’s Guide to Instrumentation Amplifiers, 3rd Edition
www.analog.comInstrumentation amplifiers (in-amps) are sometimes misunderstood. not all amplifiers used in instrumenta-tion applications are instrumentation amplifiers, and by no means are all in-amps used only in instrumentation applications. In-amps are used in many applications, from motor control to data acquisition to automotive.

Simple OP-AMP circuits
www.physics.unlv.eduApplication hint: Use precision resistors. If the two R2 resistors differ by 1% you're difference will be off by 1%. Same goes for the R1 resistors. Assume V1 = V2. If the resistors aren't matched the output won't be zero. Actually, it's better to buy a difference amplifier or an instrumentation amplifier instead of building the difference amp
