This is 80W x 2 channel, Class H, AF Power amplifer, THD = 0.8%.

The STK412-220 is a power amplifier integrated circuit (IC) produced by Sanyo Semiconductor Corporation. It is a hybrid IC that combines an analog power amplifier with a digital control circuit in one package. TheSTK412220 is designed for use in audio power amplification applications, such as audio systems in vehicles and home theater systems. It features high output power, low distortion, and good heat dissipation.

The STK412-000 series are class H audio power amplifier ybrid ICs that feature a built-in shift power supply circuit. These ICs provide high efficiency audio power amplification by controlling (switching) the supply voltage supplied to the power transistors according to the detected level of the input audio signal.
