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 term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...

[John Miller] has the perfect response next time he complains about an ache or pain and one of his friends says, “You should listen to your body!” As you can see in the video below, he already does.

Santa Clara, Calif.—National Semiconductor Corp. has introduced what it claims is the industry's first zero-drift, programmable instrumentation amplifier with on-chip diagnostics. According to ...

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 ...

This course covers the designing and building of advanced electronic circuits and systems. The approach to design is through advanced application of sensor interfacing, instrumentation and low-noise ...

Whether it’s a vision-correction medical instrument or factory press, INAs offer an excellent way to amplify microvolt-level sensor signals while simultaneously rejecting high common-mode signals. In ...
