ASSEMBLED 7W AMPLIFIERThis small amplifier is constructed around the TDA2003 IC, capable of delivering 4Wrms at 4ohms. The IC is completely thermally and short-circuit protected. A conventional direct current can be connected as supply. Features: --music power output: 7W / 4ohm--output: 3.5Wrms / 4ohm or 2Wrms / 8ohm--total harmonic distortion: 0.05% (1W / 1kHz)--frequency response: 20Hz to 20kHz (-3dB)--signal-to-noise ratio: 86dB (A weighted)--input sensitivity: 40mV / 150Kohm--overload and short-circuit protected--supply voltage: 15V DC (8 to 18V DC possible) / 0.5A--dimensions: 2.2 x 1.4" Check out more fun and exciting
