Instrumentierungsverstärkern
Instrumentierungsverstärker, often abbreviated as "Inst-Amp", are a type of differential amplifier that excels at amplifying small signals in the presence of large noise voltages. Their primary characteristic is their high common-mode rejection ratio (CMRR), meaning they can effectively suppress signals that are common to both input terminals while amplifying the difference between them. This makes them ideal for applications where low-level signals need to be measured accurately, even in electrically noisy environments.
Unlike a standard op-amp configured as a differential amplifier, instrumentierungsverstärker typically have three op-amps. Two of
Key features of instrumentierungsverstärker include their high input impedance, low input bias currents, high CMRR, and
