STK412-400 is a Class AB audio power amplifier hybrid IC from Sanyo, capable of delivering approximately 50W per channel (RMS) in a 4-channel configuration or in bridged mode. A standard circuit for this IC requires a split power supply
Because this IC generates significant heat at high power, it must be mounted to a large heat sink. Always use a heat sink compound to ensure efficient thermal transfer. stk412-400 circuit diagram
