The most used ICs are TDA2030 and TDA2003 for small audio amplifiers kits and TDA7294 for higher power amplifiers. In this article we present some representative amplifiers schematics with TDA ...

It comes in an 8-pin mini-DIP package. The IC is designed to deliver a voltage amplification of 20 without external add-on parts. But this voltage gain can be raised up to 200 (Vu = 200) by adding ...

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