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 acommon 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.
- Allowable load shorted time: 0.3 s

General Description
The STK403-400 series products are audio power amplifier hybrid ICs that consist of optimally designed discrete componet power amplifier circuits that have been miniaturized using Sanyo's unique insulated metal substrate technology. The adoption of a newly developed low thermal resisten substrate allows this product to integrate six power amplifier channels in a single compact package.
