The non-inverting amplifier is easily the most popular signal conditioning front end. This configuration is one of the simplest, most basic applications of an op amp. In college circuits courses, ...

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 ...

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 ...

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., ...

A comparator is a great circuit because it provides a near ideal transition between the analog and digital domains. The comparator looks at two linear input signals and gives a digital output that’s ...
