Audio-power-amplifier ICs suit low-power applications because of their low cost, parts count, and size. Applications demanding higher output power challenge designs based on IC power amplifiers. The ...

Over the last 5 years some outstanding advances have been made in monolithic operational amplifiers. These devices have progressed from the point where they were an expensive curiosity, with marginal ...

What if a palm-sized amp could outperform larger, more expensive modules while delivering serious sound quality? Check out this 60-W amplifier design.

Amplifiers are fundamental circuit-design elements. They drive everything from earbuds to antennas. Placed ahead of analog-to-digital converters (ADCs), they reshape signals from sources as diverse as ...

Back in the '60s, there was an intriguing circuit article titled "Starved-Circuit Amplifier" published in Popular Electronics magazine. It used a sharp cut-off pentode with a 3-MO load resistor and ...

Component distributor Richardson RFPD has prepared a couple of documents on the options available for designers of RF amplifiers. Rather than in-depth, they are a useful introduction to the different ...

Dan D’Agostino Master Audio Systems has announced the launch of the Momentum Z Monoblock Amplifier at $125,000 per pair amd with an an output of 500W per channel.

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 ...
