The STK412-530 requires a split (±) power supply. Due to its Class H architecture, it requires two pairs of supply voltages: a "low" voltage (±VCC_L) for the output stage quiescent bias and normal operation, and a "high" voltage (±VCC_H) that is switched in only when large signal peaks demand more voltage swing. Power Output Capabilities Pins for the feedback loop
In the world of analog audio amplification, few components evoke as much respect (and frustration) as Sanyo’s STK series. The is a member of the prestigious "Series II" thick-film hybrid ICs. If you are searching for its datasheet, you likely aren't just curious—you are either designing a high-end vintage stereo repair or troubleshooting a dead channel on a beloved amplifier.
. It is designed for high-efficiency audio amplification by using a "shift power supply" that switches voltage based on the input signal level.
