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 ...

What if a palm-sized amp could outperform larger, more expensive modules while delivering serious sound quality? Check out ...

This is a 35W audio power amplifier built with TDA2030 in a bridged connection with a +- 15V symmetric PS. It is easy to build, do it yourself audio amplifier which will deliver up to 35W on a 8Ω ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

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 ...

New operational amplifiers optimized for high-performance audio and ultrasound applications combine extremely low total harmonic distortion plus noise (THD+N), -130 dB, with large output voltages on ...

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 ...

Dan D’Agostino Master Audio Systems has announced the launch of the Momentum Z Monoblock Amplifier at $125,000 per pair amd ...
