This Design Idea offers a new instrumentation-amplifier topologythat improves ac CMR (common-moderejection). Because it uses discrete amplifiers,you can customize it for the lowestpower, price, noise, ...

Instrumentation amplifiers find wide use in real-world data acquisition. However, designers often incorrectly apply them. Specifically, although modern in amps have excellent CMR (common-mode ...

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., ...

Benefits of using an indirect current-mode instrumentation amplifier for large differential offsets. Design specs for a low-power application. Key design considerations when implementing an in-amp ...
