The Intersil ISL2853x/63x series IAs are pretty cool devices. These are a series of instrumentation amplifiers based on the usual three-op-amp configuration. They are built on a low-voltage process, ...

The debate still goes on as to which are better, valves or transistors. We don’t intend to get involved in that argument here. But if you can’t make your mind up, you should try out this simple ...

[Ynze] has built an audio amplifier that looks and sounds great. His amplifier uses a National Instruments (now TI) LM3886 Overture series 68 Watt power amp. The LM3886 places [Ynze’s] amp squarely in ...

If you think most components are too complicated and just want great sound, the no-frills Cambridge AXA35 integrated amplifier is exactly what you’re looking for. Ex-movie theater projectionist Steve ...

Pathos’s Inpol Remix MkII is an easy amplifier to underestimate. It’s about the size of a child’s shoebox and has a modest claimed power output of just 25 watts per channel into 8 ohms. That’s the ...

While surround sound, wireless, and multiroom audio tend to generate the biggest buzz these days, many audio enthusiasts still swear by a relatively simple amp with two channels — preferably analog.

At only $1,499 USD, the Naim CI-Uniti 102 feels like a streamlined Uniti Atom in a pair of skinny jeans. Depending on how many sources you still use and the size of your listening space, the Naim ...

One of my first jobs as a freshly minted graduate engineer involved the maintenance of a set of analogue chart recorders. They were museum pieces by the early 1990s: a motorized roll of graph paper ...

In a signal-conditioning op-amp application, is there an optimum circuit topology for optimizing SNR and SFDR? Here’s a succinct analysis, part mathematical, part simulation, and part cookbook, from ...
