Fosi Audio ZH3 DAC/Headphone Amp/Preamp offers balanced outputs, ultra-low noise, high-res support, and replaceable op-amps for $199.99. Fosi Audio has officially unveiled the ZH3, an all-in-one ...

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) are almost the perfect amplifiers. As long as you keep a few important details in mind, they will seem perfect. In part 1, I gave a simplified explanation of how an op ...

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 ...

An instrumentation amplifier (INA) built using three operational amplifiers (op amps) can provide performance advantages in terms of high input impedance, low output impedance, easily adjustable gain, ...

Zero-drift amplifiers have the lowest input offset voltage (Vos) and offset voltage drift of any operational amplifier (op amp) topology. Compared to best-in-class precision low-input offset-voltage ...

In this lab we introduce the operational amplifier (op amp), an active circuit that is designed with certain characteristics (high input resistance, low output resistance, and a large differential ...

Switching regulators have delivered such convenience and efficiency compared to their linear siblings, that it’s now becoming rare to see an old-style three-terminal regulator. Modern designs have ...

Abstract: This article presents a new approach to automate the setup of the design equations of the manual analog design process. Its main contribution is a comprehensive hierarchical performance ...
