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, ...

Building on last month’s discussion of resistor noise, let’s check out some basics of amplifier noise. The non-inverting op amp configuration is most common for low noise applications so we’ll make ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...

Op-amps are among the most widely used electronic devices, and are designed into many consumer, industrial, and scientific devices. General purpose, standard op amps sell for well under one dollar.

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 ...

In the world of audiophilia there are arguments that rage over the relative merits of particular components. Sometimes this can reach silly levels as in the high-end ALPS pot we once saw chosen as a ...
