20W stereo amplifier based LM1876
This two-channel amplifier provides power to 20 watts RMS from two line inputs. Ideal for use in computers since its price / performance / complexity is optimal. In the 20 watt stereo amplifier circuit observed only one stage of the system because the circuit stereo, second channel are identical. The figures in parentheses are equivalent to the terminal for second channel. The core of this project is the integrated circuits from National Semiconductor, the LM1876, which provides two power operational amplifier with mute and standby function.
