Delivers a robust 100W to 150W per channel into an 8Ω load.
(Pins 13–22 are typically NC (Not Connected) or auxiliary pins for internal biasing. Always verify with your specific datasheet.) Stk412-230 Datasheet Pdf
Unlike traditional Class‑AB amplifiers that run at a fixed high voltage regardless of signal strength, the STK412‑230’s shift power supply circuit based on the incoming audio signal. This delivers Class‑A/B‑grade sound quality with far less wasted heat and lower power consumption—a major advantage for audio installations where cooling is limited.
The is a two-channel, class-H audio power amplifier hybrid integrated circuit (IC) originally developed by SANYO Electric Co., Ltd. (now part of Panasonic). It is designed for high-efficiency audio amplification, specifically delivering 150W + 150W of power. Core Specifications Amplifier Class: Class H. Output Power: 150W + 150W. Package Type: SIP18 (Single In-line Package with 18 pins).
