You can implement many fundamental building-block circuits such as a difference amplifier (DA) or instrumentation amplifier (IA) using discrete or integrated components. Design engineers often debate ...

Proof positive that not all watts are created equal. Especially those designed by Nelson Pass. Lest one think that this review is simply not only more evidence that I have somehow formed an untoward ...

As the saying goes, hindsight is 20/20. It may surprise you that the microchip that we all know and love today was far from an obvious idea. Some of the paths that were being explored back then to ...

Integrated amplifiers have become very popular again with audiophiles for a few reasons and we think it’s fair to say that expensive separates are becoming less relevant. Build quality matters.

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 ...

The circuit was based on a single operational amplifier integrated circuit that is made to produce a modular preamplifier which functions in the Class A operation Preamplifier (pre-amp) – a device ...

You’re probably familiar with the little black boxes nestled neatly inside your favorite devices. With their diminutive size and unassuming characteristics, it can be hard to believe these vessels are ...
