Product Summary

The STK415-130 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. The STK415-130 is suitable for Audio power amplifiers.
