    20 Watt Stereo Audio Power Amplifier by LM1875

    Posted Jan 24, 2012 By Circuit Projects

    Here is a reliably high sound quality audio power amplifier project based on the National Semiconductor’s LM1875 IC. The circuit that we give is a similar form of the application circuit in the datasheet that NS provides. It is really easy to build and low cost. The voltage gain of the…
