Thick-Film Hybrid IC
STK412-150C-E
Two-Channel Power Switching System
Audio Power IC, 150W+150W
Overview
The STK412-150C-E is a class H audio power amplifier hybrid IC that features a built-in power supply switching circuit.
This IC provides high efficiency audio power amplification by controlling (switching) the supply voltage supplied to the
power devices according to the detected level of the input audio signal.
Applications
• Audio power amplifiers.
Features
• High output power by using power MOSFETs.
• Output load impedance: RL = 8Ω to 6Ω supported
• Using insulated metal substrate that features superlative heat dissipation characteristics that are among the highest in the
industry.
