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.

• Allowable load shorted time: 0.3 s
