Designing the instrumentation amplifier, with its few external components, appears to be a simple task, but to obtain a reliable design, you must avoid certain traps. You must correctly match 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 ...

The instrumentation amps I covered in my last column are difference amps made with internal resistors (Reference 1). Difference amps have high CMR errors when you use ...

Many industrial and medical applications use instrumentation amplifiers (INA) to condition small signals in the presence of large common-mode voltages and DC potentials. The three op amp INA ...
