Overview
The STK412-000 series are class H audio power amplifier
hybrid 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.
Features
• Pin compatible IC series that covers power ratings from
• The pin arrangement is also unified with that of the
• Miniature package

three-channel STK413-000 series. This means that PCBs
designed for three-channel models can also be used for
two-channel models.
