In my previous article on common op-amp circuits, I mentioned that operational amplifiers were used for analog computing, where analog circuits simulated the behavior of complex systems. That article ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) In the first article of this series, “Operational Amplifier–The Basic Building Block” ...

You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do that with a 555,” [Doctor Volt] might say, “you can do that with an op amp ...

If you’re designing a linear circuit of any kind today, it most likely involves an op amp and even an analog-to-digital converter (ADC). The op amp is your go-to device simply because it can be ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...
