: Amplified audio signal out to the speaker network. VCC (+) : Positive high-power supply rail.
The STK412-230 series typically uses a unified pin arrangement, making it pin-compatible with other models in the series (ranging from 50W to 180W). This allows manufacturers to use a common PCB for different power classes. : Requires a dual/symmetrical power supply ( +VHpositive cap V sub cap H +VLpositive cap V sub cap L −VLnegative cap V sub cap L −VHnegative cap V sub cap H
The STK412-230 comes in an 18-pin Single Inline Package (SIP). The datasheet provides a standard pinout that is unified across the STK412-000 series. Key pins include: | Parameter | Rating | | :--- |
