This small amplifier is constructed around the TDA2003 IC, capable of delivering 4Wrms at 4 Ohm.
The IC is completely thermal and short-circuit protected.
A conventional DC supply can be used.
Technical Specifications:
- Musical power output : 7W/4 Ohm
- RMS output : 3.5W/4 Ohm and 2W/8 Ohm
- Total harmonic distortion : 0.05% (1W/1 KHz)
- Frequency reproduction : 20 Hz to 20 KHz (-3dB)
- Signal/noise ratio : 86dB (Weighted A)
- Input sensitivity : 40 mV / 150 KOhm
- Overload and short-circuit protected
- Supply Voltage : 15 VDC (8 to 18VDC possible) / 0.5A
