This “Product How-To” article focuses how to use a certain product in an embedded system and is written by a company representative. Audio amplifier products are becoming more and more advanced in ...

This is a simple circuit which I built to one of my audio amplifier projects to control the speaker output relay. The purpose of this circuit is to control the relay which turns on the speaker output ...

From earlier work in this series, distortion from the small-signal stages may be kept to levels that will prove negligible compared with distortion from a closed-loop output stage. Similarly, future ...

This article started because a good friend of mine dropped a Panasonic SA-XR50 switch-mode amplifier to me for some basic bench test. This article will NOT be a review of that unit, but an ...

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...

When used with other blocks and modules, a new approach to modeling operational-amplifier output impedance behavior can provide a more realistic overall behavioral model. Simulating the behavior of a ...

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...
