The STK412-230 is a 2-channel audio power amplifier IC with a built-in thermal shutdown circuit and mute function. It is designed to deliver high-quality audio with low distortion and high power output. The IC operates on a single power supply voltage ranging from 10V to 40V and can drive a load impedance of 4 ohms.
High-efficiency stereo audio systems, subwoofers. STK412-230 Key Features
The is a two-channel, thick-film hybrid audio power amplifier IC manufactured by Sanyo (now part of Panasonic). Part of the STK412-000 series , it is specifically designed for high-efficiency audio amplification using a Class H architecture with a built-in shift power supply circuit. Key Specifications & Features STK412-230
Placed as close to the IC power pins as possible (typically 100 F electrolytic parallel with 0.1 F ceramic) to eliminate power rail ripple. Zobel Network: An RC series network (usually a 10 Ωcap omega resistor and 0.1
