Overview
The STK416-090-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 detectedlevel of the input audio signal.

FEATUREs
•Pin-to-pin compatible outputs ranging from 80W to 180W.
•Can be used to replace the STK415-100 series (2-channel models) and the class-AB series (2, 3-channel models) due to its pin compatibility.
•Pure complementary construction by new Darlington power transistors
•Output load impedance: RL= 8Ω to 4Ω supported
•Using insulated metal substrate that features superlative heat dissipation characteristics thatare among the highest in the industry.

APPLICATIONs
•Audio power amplifiers.
