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 ...

Editor’s note: Here’s an oldie but goodie. EDN editors regularly field requests for copies of articles that predate our online archive, but this Design Idea from our Feb 20, 1986, issue has generated ...

An instrumentation amplifier is the intermediate stage of a instrumentation system. The signal source of the instrumentation amplifier is the output of the transducer. Many transducers output do not ...

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 ...

When something is described as “Low Noise”, it is by the nature of the language a relative phrase. The higest quality magnetic tape is low noise compared to its cheaper sibling for example, but still ...

It’s been a running battle in some quarters for years, whether analog sensor processing is better than digital. Proponents of digital are sometimes driven by lack of familiarity with analog circuitry, ...

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 ...

The most common device for the measurement of load, pressure, torque, and even piezo-resistive (low frequency) acceleration is the strain gauge transducer. As a transducer, which converts a measured ...

Using the circuits below you can study op amps and characterize their behavior. Comparator Inverting Amplifier The comparator demonstrates the ``open-loop'' behavior of an op amp. You can design the ...
