8 Watts Audio Amplifier (TDA2003)

Hosted circuit

This circuit is also Crossed to: Amplifiers

Nice small audio amplifier which use only few parts to give good quality sound. This amp can be used as a simple booster, the heart of a more complicated amplifier or used as a guitar amp. Although not perfect, this amplifier does have a wide frequency response, low harmonic distortion about 1.5%, and is capable of driving an 8 ohm speaker to output levels of around 8 watts with slightly higher distortion.

Any power supply in the range 12 to 18 Volts DC may be used.

Have a look at the TDA2003s datasheet(from where this circuit originates). You'll find a PCB layout and all you asked for.

You can buy a kit or a ready-assembled board (just add battery, input and output connections) from www.maplins.com
