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, ...

[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 ...

In Seemingly Simple Circuits: Transresistance Amplifier, Part 1– Approximating Op-Amps, the op-amp was approximated from a single-pole, finite gain amplifier to an infinite-gain, single-pole op-amp, ...

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 ...

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 ...
