This is an improvement over similar circuits that place the variable gain element in the op amp feedback circuit where it supports high signal voltages and subsequently introduces significant ...

Here’s a nostalgic vibe of an awesome analog chip from the 1990s era that’s still making an impact in audio designs.

Unlock the potential of the TDA2003 with a high-efficiency 10W audio amplifier circuit designed for clean and powerful sound output. This simple yet effective design ensures optimal performance ...

The goal was to keep the circuit simple and the number of amplification stages to a minimum while having enough gain to be driven by most preamplifiers, solid-state or vacuum tube. This suggested ...

International Solid-State Circuits Conference in San Francisco always seems to make space for audio amplifier developments, and this year is no exception, with some extraordinary distortion and noise ...

The circuit is simple and only produces a small negative voltage. He mentions that into a 910 ohm load, he sees about -0.3V. Not much, but enough to get that op amp down to zero with a reasonable ...
