Stk412-230 Datasheet Pdf Jun 2026
To build a reliable amplifier using the STK412-230 datasheet guidelines, several peripheral circuits must be implemented:
STK412-230 is a two-channel, Class H audio power amplifier hybrid integrated circuit (IC) manufactured by
The STK412-230 is designed to bridge the gap between high-power demand and compact design. Its standout feature is the , which enables Class H operation. This allows the IC to switch supply voltages dynamically based on the input signal level, significantly reducing heat dissipation and improving overall efficiency.
The STK412-230 belongs to the STK412-xxx series of hybrid power ICs. It stands out due to its "Shift Power Supply" technology, which is a variation of Class H amplifier design. This design enables the amplifier to achieve higher efficiency compared to traditional Class AB amplifiers by managing the supply voltage based on the input signal level. High Power Output: Designed for robust stereo output. Stk412-230 Datasheet Pdf
Provides detailed information on the component and its applications. Conclusion
To help you move forward with your project, please let me know:
The STK412-230 is housed in a . The precise pin configuration (pinout) is crucial for proper circuit board design and troubleshooting. While the exact pinout needs to be verified from the official datasheet, it generally includes connections for high and low power supply voltages, audio input signals, audio output signals, ground, and standby/mute functions. The unified pin arrangement also matches that of the three-channel STK413-000 series, adding another layer of design flexibility. To build a reliable amplifier using the STK412-230
Reading a blog summary is fine, but you get the original PDF for three reasons:

The STK412-230 is a 2-channel audio power amplifier IC that operates on a single power supply voltage. It is designed to deliver high-quality audio with low distortion and high output power. The IC features a compact package, making it suitable for use in a wide range of applications.
Less than 0.4% at rated power across standard audio bandwidths
Generally rated around 100W to 150W per channel (depending on load impedance and VCC supply)
High / Low): Because it operates on a Class H architecture, the chip features separate pins for low-voltage rails ( VCCcap V sub cap C cap C end-sub L) and high-voltage rails ( VCCcap V sub cap C cap C end-sub
The datasheet will typically show a vertical, multi-pin package (usually 15 to 18 pins). Key pin groups to identify on the datasheet are:
