The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

If you’ve ever wondered why an op amp has the little plus and minus symbols on it, its because at the heart of it, the device is a differential amplifier. The problem is that — ideally, at least — it ...

Let me shatter your confidence in simplicity! You think that applying an op amp is as simple as using a non-inverting circuit: Let me shatter your confidence in simplicity! You think that applying an ...

There is an occasional caution that even unity-gain stable Voltage Feedback Amplifiers (VFAs) risk instability in inverting attenuator applications (Reference 1). In fact, there should be no more ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

Download this article in PDF format. When talking amplifiers, I sometimes get the impression that whole groups of electronics hobbyists and engineering students have been brainwashed by endlessly ...
