AmplifierCircuits

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  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 50 W/ch to 120 W/ch (THD = 0.8%, f = 20 Hz to 20  kHz): 64 × 36.5× 8.5 mm* 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.
