This unique small audio power amplifier is designed around the TDA1521 IC. The IC is
thermal, short circuit, and overload protected for reliable operation. One of the neat
features of this amplifier is that it needs no additional rectifier and smoothing filter
because it can also run on AC!
The small board and custom heatsink design make installation and connection a breeze. Just connect your inputs, your
speakers (4 or 8 ohm) and power. Don’t worry about overloads, or shorts on your outputs because it has automatic
protection.
In addition, transient suppression is switchable on/off as desired. If you’re looking for a sweet little inexpensive stereo
amplifier, this is for you! Board, less heatsink, measures 2.8” x 2”. From Velleman.

This compact 10W (5W + 5W) stereo amplifier is based on two TDA2003 Integrated
Circuits. The small size, as well as the low harmonic and cross-over distortion, make
it great for kiosks! Also well suited for connection to your portable MP3 players to allow
them to be connected to standard speakers. Completely safe operation is guaranteed
thanks to protection against DC and AC short circuits, thermal over-range, load dump voltage surge
up to 40V and open ground conditions. Comes with a 3.5mm stereo audio input jack, plus screw-on terminals for
speaker outputs!. From CanaKit.
Great for kiosk applications!
Low harmonic and crossover distortion!
Short circuit and overload protected!
Custom silk screened enclosure available!

A compact mono 5W amplifier based on the TDA2003 Integrated Circuit, this lit-
tle kit packs a punch! Thanks to it’s small size and low harmonic and cross-over
distortion, this kit is ideal for all kinds of audio amplification applications, especially
kiosks or similar applications where a small amp is required!
One really neat feature, considering that pretty much all audio sources these days will be
stereo, this amplifier provides stereo inputs and then mixes both channels into a single ampli-
fied mono channel! Sure beats the good old days of plugging just one side in and hoping for
the best! Completely safe operation is guaranteed due to protection against short circuits, thermal over-range, load dump voltage surges and open ground situ-
ations. It comes with a built-in 3.5mm stereo audio input jack plus screw terminals for the speaker output for easy wiring! From CanaKit.
