TDA2003 often used in car stereo amp car in the low-power integrated amp with very little additional elements can give a single channel mono 10watt power. Anfi … 10v 8v circuit operating voltage from a single source
TDA2003 10W Car Radio Audio Amplifier
The TDA 2003 has improved performance with the same pin configuration as the TDA 2002. The additional features of TDA 2002, very low number of external components, ease of assembly, space and cost saving, are maintained. The device provides a high output current capability (up to 3.5A) very low harmonic and cross-over distortion.

2W Amplifier Circuit LA4182
2 watts summer look that many computer users within the mini-500w sound system than the quality of integrated 2W Amplifier la4182’s 🙂 circuit can operate with supply voltages from 5v … 9v.
LA4182 2-Channel AF Power Amplifier
Built-in 2 channels enabling use in stereo and bridge amplifier applications. High output: 2.3 W/channel, VCC = 9 V, RL = 4 W, and 4.7 W/bridge, RL = 8 W. Minimum number of external parts required : 9 pcs. min. (Stereo/bridge). Small pop noise at the time of power supply ON/OFF due to built-in muting circuit. Good ripple rejection ratio due to built-in ripple filter. Soft tone at the time of output saturation. Good channel separation. . Voltage gain fixed at 45 dB (Bridge: 51 dB)
