Thick-Film Hybrid IC
STK412-170
Two-Channel Shift Power Supply Audio Power Amplifier ICs
180W + 180 W
Overview
Package Dimensions
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.

• 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
