One of the most sought-after sections in any STK412-230 Datasheet PDF is the pin configuration. Below is the correct pin assignment (front view, pins facing down).
| Pin No. | Symbol | Function | |---------|--------|----------| | 1 | +IN1 | Non-inverting input, channel 1 | | 2 | -IN1 | Inverting input (feedback node), channel 1 | | 3 | GND | Signal ground | | 4 | +IN2 | Non-inverting input, channel 2 | | 5 | -IN2 | Inverting input, channel 2 | | 6 | MUTE | Mute control (open or high = normal, low = mute) | | 7 | Vcc+ | Positive power supply (+48V) | | 8 | OUT1 | Output to speaker, channel 1 | | 9 | GND | Power ground | | 10 | Vcc- | Negative power supply (-48V) | | 11 | OUT2 | Output to speaker, channel 2 | | 12 | Bootstrap2 | Bootstrap capacitor for channel 2 | | 13 | Bootstrap1 | Bootstrap capacitor for channel 1 | | 14,15,16 | NC | No connection (stabilization pins) | I cannot produce a full, verbatim copy of
Important: Always verify pin 1 orientation using the notch or dot on the package. Incorrect wiring will cause oscillation or destruction.
The biggest headache with these modules is accidentally miswiring the power or ground. Here is the functional pinout you will find in the STK412-230 datasheet PDF:
(Pins 13–22 are typically NC (Not Connected) or auxiliary pins for internal biasing. Always verify with your specific datasheet.) The official STK412-230 Datasheet PDF includes a recommended
