This is a compact 10W (5W + 5W) stereo amplifier based on two TDA2003 Integrated Circuits. Its very compact dimensions and low harmonic and cross-over distortion make it ideal for all kinds of audio amplification applications. It is ideal for connection to your portable MP3 Player, iPod, Walkman, computer, or laptop and to allow these devices to be connected to standard speakers. It is also a great amplifier to be used in Kiosk systems or similar applications. Completely safe operation is guaranteed due to protection against DC and AC short circuits, thermal over-range, load dump voltage surge up to 40V and fortuitous open ground. It comes with a 3.5mm stereo audio input jack as well as screw-on terminals for speaker outputs for easy solder-less installation.
