24W Bridge Amplifier Circuit with TDA2006

This is a bridge amplifier circuit which built using dual power IC TDA2006. Each IC capable to deliver 12W power audio output as explained on TDA2006 12W amplifier circuit. The double TDA2006 will also double the gain.

Here the circuit design diagram:

About TDA2006:
The power amplifier IC TDA2006 provides high output current and has very low harmonic and cross-over distortion. Further the device incorporates anoriginal (and patented)short circuit protection system comprising an arrangement for automatically limiting the dissipated power so as to keep the working point of the output transistors within their safe operating area. A conventional thermal shutdown system is also included.

About Audio Amplifier
An audio amplifier is an electronic amplifier that amplifies low-power audio signals (signals composed primarily of frequencies between 20 - 20 000 Hz, the human range of hearing) to a level suitable for driving loudspeakers and is the final stage in a typical audio playback chain.
The preceding stages in such a chain are low power audio amplifiers which perform tasks like pre-amplification, equalization, tone control, mixing/effects, or audio sources like record players, CD players, and cassette players. Most audio amplifiers require these low-level inputs to adhere to line levels.
While the input signal to an audio amplifier may measure only a few hundred microwatts, its output may be tens, hundreds, or thousands of watts. More explanation about power audio amplifier can be found at wikipedia.org
This is the video tutorial about how to build a realy simple headphone amplifier. The circuit powered with 9V battery and use an IC to amplify the input signal from mp3 player.
