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, ...

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 ...

Last month we explored noise of the non-inverting amplifier but I dodged the issue of the feedback network’s noise contribution. A reader, Jim, challenged me—he wanted more detail. So what about the ...

The schematic in Figure 1 is a common summing amplifier with multiple inputs and one single-ended output. It is a variation of a standard inverting amplifier. Point X is a virtual ground and is ...

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 ...

This file type includes high-resolution graphics and schematics when applicable. Most data-acquisition systems with wide dynamic range need a method of adjusting the input-signal level to the ...
