7 Watt Audio Amplifier Using TDA2003

Amplifier Circuits Diagram

Schematic diagram of a simple 7 watt audio amplifier using TDA2003 Amplifier IC. This is a good IC with many built in features like low harmonic distortion, short schema protection,thermal overload protection etc. This IC is a upgrade version of TDA 2002 amplifier IC.

  1. merge foarte bine si fide condensatorul de 1000 si cevade pico puneti fix 1000 (102) ca fidelitate este bun si ca putere cam 5w in 8r
