We took a look at op amp integrators in the previous article, Op amps do integration, so it makes sense to round out the picture by covering differentiator circuits. Of course, differentiation is the ...

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 ...

We are all used to the op-amp, as a little black box from which we can derive an astonishingly useful range of circuit functions. But of course within it lurks a transistor circuit on a chip, and u… ...

These devices are really only different because they separate the functions of creating a high input impedance and amplifier gain in independent sections of laboratory precision circuitry. The op-amp ...

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.

An op amp is an amplifier circuit made from several stages, each of which contributes to the overall voltage gain and to the isolation of the output circuit from the input connections.
