7W Mono Audio Amplifier

• Music power output: 7W / 4ohm
• RMS output: 3.5W / 4ohm or 2W / 8ohm
• Total harmonic distortion: 0.05% (1W / 1kHz)
• Frequency response: 20Hz to 20kHz (-3dB)
• Signal/noise ratio: 86dB (A weighted)
• Input sensitivity: 40mV / 150Kohm

This 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.
Overload and short-circuit protected. Supply voltage: 15V DC (8 to 18V DC possible) / 0.5A. Dimensions: 2.2" x 1.4"
K4001 is kit, M4001 is assembled.
