A two-channel shift power supply audio power amplifier is a type of audio amplifier that uses a shift power supply topology to provide power amplification for audio signals. An audio power amplifier is an electronic device that takes a low-level audio signal and increases its power to a level suitable for driving loudspeakers or other types of audio output devices. The primary purpose of an audio power amplifier is to amplify the audio signal to a sufficient level for reproducing sound with the desired volume and quality.

Description
This is Two-Channel Shift Power Supply Audio Power Amplifier ICs 60W + 60 W.
The STK412-000 series are class H audio power amplifier hybrid ICs that feature a built-in shift power supply circuit. These Provide ICs 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.
Features
• Pin compatible IC series that covers power ratings from 50 W × 2 channels to 180 W × 2 channels at 0.7 or 0.8% THD, 20 Hz to 20 kHz. This allows the use of a common PCB for all output classes.
• The pin arrangement is also unified with that of the three-channel STK413-000 series. This means that PCBs designed for three-channel models can also be used for two-channel models.
• Miniature package
(1) 50 W/ch to 120 W/ch (THD = 0.8%, f = 20 Hz to 20 kHz): 64 × 36.5× 8.5 mm-
(2) 150 W/ch to 180 W/ch (THD = 0.7%, f = 20 Hz to 20 kHz): 78 × 44× 9 mm- – Not including the IC pins.
• Allowable load shorted time: 0.3 s
