Op amps. Often the first thing that many learn about when beginning the journey into analog electronics, they’re used in countless ways in an overwhelmingly large array of circuits. When we think ...

We analog designers take great pains to make our amplifiers stable when we design them, but there are many situations that cause them to oscillate in the real world. Various types of loads can make ...

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 ...

Operational amplifiers (op amps) play many different roles in optimizing the performance of mixed signal system design. Today’s mixed signal designer is challenged to understand the requirements of ...

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 ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

How do you get the input of an op-amp to work below the negative-most supply rail?, I asked. Now I know – thanks to the patience of ADI field application engineer Andreas Koch. It was not just any ...

Rohm has introduced a tiny nano-power rail-to-rail op-amp for sensor amplification, in a 910 x 800μm WLCSP (wafer-level chip-scale package). TLR1901GXZ, as it will be known, is CMOS and has a maximum ...

You can take an op amp with rare input characteristics and elevate it to achieve higher voltage range, better gain accuracy, higher slew rate, and less distortion than the original op amp. I was ...
