If anyone has a clean PDF or can confirm: Stk411-210e Datasheet
The core components of a typical application circuit would include: The module is packaged in a compact 11-pin
The STK411-210E is a 2-channel power amplifier module that operates on a single power supply voltage. It is designed to deliver high-quality audio performance with low distortion and high output power. The module is packaged in a compact 11-pin SIP (Single In-line Package) format, making it easy to integrate into various audio equipment. Power Supply Positive ( +VCCpositive cap V sub
