Mono amplifier, 7W Mono Audio Amplifier Kit

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. The musical power output is 7W for 4 Ohm amd tje RMS output is 3.5W/4Ohm and 2W/8Ohm. Total harmonic distortion is 0.05%(1W/1KHz) and frequency reproduction is 20Hz to 20KHz(-3dB). The signal/noise ratio is 86dB (weighted A) and input sensitivity is 40mV/150KOhm. The circuit is protected from short-circuit and overload.
