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 ...

A lot of the analog-circuit conversation these days is centered on low-power and thus low-voltage considerations. That makes sense for operational amplifiers (op amps), of course, since these basic ...

A few months ago, I wrote a Signal Chain Basics article titled “3 considerations when selecting an op amp.” While that article is very useful for selecting operational amplifiers (op amps) for new ...

As analog engineers, it’s tempting to fantasize about one day coming close to designing the ideal operational amplifier we encountered in college: infinite bandwidth, zero output resistance, and so on ...

In the first article about measurement systems we looked at sensors as a way to bring data into a measurement system. I explained that a sensor measures physical quantities which are turned into a ...

Are your jellybeans getting stale? [lcamtuf] thinks so, and his guide to choosing op-amps makes a good case for rethinking what parts you should keep in stock. For readers of a certain vintage, the ...
