Op amps are the fundamental building blocks of analog circuits; you can build all analog functions from op amps. Add digital output circuitry to an op amp to get a comparator that can also function as ...

Designers now have available a broad collection of instrumentation amplifier (in-amp) design circuits for dual supplies. However, there also is a growing use of the single-supply amps, especially in ...

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 ...

It is widely accepted that you cannot build a precision differential amplifier using discrete parts and obtain good CMR performance or gain accuracy. This is due to the matching of the four external ...

These days there a large number of sensors and analog circuits that are “controller friendly” meaning that their output signal is easily interfaced to the built-in Analog to Digital Convertors (ADCs) ...

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 ...

What does an instrumentation amplifier do? An instrumentation amplifier (also known as an in amp) measures small signals in the presence of a noisy environment. The noise generally is common-mode ...
