As instrumentation amplifiers become less costly, they can provide improved performance in applications that operational amplifiers traditionally served. The op-amp adder in Figure 1 has a few ...

This three-part article about instrumentation amplifiers (IAs) discusses common-mode versus differential-mode signaling, basic operation of the traditional 3-op amp topology, and how to interpret and ...

In the past, the term instrumentation amplifier (INA) was often misused, referring to the application rather than the device’s architecture. INAs are related to op amps, in that they’re based on the ...

Even during routine operation of an instrumentation amplifier, a fault can develop between the sensor and the amp. This fault could result from misuse, the environment, or low-quality assembly, among ...
