If you have read my first blog, you may have noticed that I really like op amps. My primary expertise lies in designing them, but I’m also intrigued by clever op-amp application circuits. To promote ...

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 ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

Professional speakers have two types of outputs identified as high and low level. The high-level outputs are used for the main speakers since they amplify the left and right speakers. Generally, the ...

In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...

Fosi Audio ZH3 DAC/Headphone Amp/Preamp offers balanced outputs, ultra-low noise, high-res support, and replaceable op-amps for $199.99.

ROHM’s ultra-compact complementary metal–oxide–semiconductor (CMOS) operational amplifier (op amp) TLR1901GXZ achieves the ...

August 4, 2008 Of all the equipment we use in our hi-fi and home theater systems, the thing that’s changed the least over the past 20 years is the speaker. After all, there’s only so many ways you can ...
