This small amplifier is constructed around the TDA2003 IC, capable of delivering 4Wrms at 4 ohms. The IC is fully protected against overheating and short circuits. A conventional direct current is sufficient as power supply.
Features:

1. exists also in mounted version: WMAH114

Specifications:

1. music power output: 7W / 4ohm
2. RMS output: 3.5W / 4ohm or 2W / 8ohm
3. total harmonic distortion: 0.05% (1W / 1kHz)
4. frequency response: 20Hz to 20kHz (-3dB)
5. signal/noise ratio: 86dB (A weighted)
6. input sensitivity: 40mV / 150Kohm
7. overload and short-circuit protected
8. supply voltage: 15VDC (8 to 18VDC possible) / 0.5A
9. dimensions: 55 x 35mm / 2.2 x 1.4"
