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 them with high-resistance sensors ...

In the first article about measurement systems we looked at sensors as a way to bring data into a measurement system. I explained that a sensor measures physical quantities which are turned into a ...

The XTR105, XTR112, and XTR114 from Burr-Brown are a family of two-wire, 4-20 mA current-loop transmitters with instrumentation-amplifier input stages. The front end is designed to be used with a ...

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 ...
