Some DIY modules on the market may only provide a single set of supply voltage inputs by internally deriving the low voltage from the high voltage supply. Always verify the specific requirements of your PCB before application. The STK412-530 is a two-channel Class H audio

Positive and negative input for Channel 1 and Channel 2. Feedback Pins: To control gain and minimize distortion. Power Supply Pins: Dual voltage inputs ( ) to feed the shift power supply. Ground: Signal and Power Ground. Output Pins: Speaker outputs for both channels. Always verify the specific requirements of your PCB

According to the official STK412-530 datasheet, the following parameters define its operational limits: ±60V to ±70V (Varies by load) Supply Voltage ( VLcap V sub cap L max) ±40V to ±45V Output Power 100W + 100W (Typically at 6Ω) Total Harmonic Distortion (THD) 0.8% (at rated output) Load Impedance 6Ω (Optimized) Operating Temperature Up to 125°C (Case temperature) 3. Pinout Configuration

: This IC often employs a shift power supply configuration for improved efficiency in various audio setups.

The STK412530 is a class AB audio power amplifier IC designed by SANYO Electric Co. (now part of ON Semiconductor). It is a dual-channel (stereo) amplifier capable of delivering 30 watts per channel into a 6-ohm load (or 25W into 8 ohms) with low distortion. It is built using SANYO’s proprietary thick-film hybrid technology, which combines discrete transistors, resistors, and capacitors on a ceramic substrate, all encapsulated in a plastic package.
