   What are instrumentation amplifiers (in-amps)?

   • Instrumentation 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.

   May 2, 2018 · Instrumentation amplifiers offer very high impedance, isolated inputs along with high gain, and excellent CMRR performance. Some people like to think of instrumentation amplifiers as a form of “souped up” differential amplifier. Instrumentation amplifiers can be fashioned from separate op amps.
