The pinout follows the typical STK412 series arrangement, with channel A (Left) on pins 15-16 and channel B (Right) on pins 2-3. The non-inverting inputs (pins 3 and 15) are normally connected to the audio input signal through a coupling capacitor, while the inverting inputs (pins 2 and 16) are used for the feedback network.

The is a two-channel, high-efficiency Class H audio power amplifier hybrid IC manufactured by Sanyo (now part of ON Semiconductor). Designed for high-fidelity audio systems and home theaters, it utilizes a "shift power supply" circuit to switch supply voltages based on the input signal level, significantly improving efficiency and reducing heat.
