| 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) | Always verify pin 1 orientation using the notch or dot on the package. Incorrect wiring will cause oscillation or destruction. Part 4: Electrical Characteristics (from the STK412-230 Datasheet) The following values are typical for Vcc = ±48V, RL = 6Ω, f = 1kHz, Tc = 25°C.

| Parameter | Symbol | Conditions | Rating | Unit | |-----------|--------|------------|--------|------| | Maximum Supply Voltage | Vcc max | No signal | ±55 | V | | Recommended Supply Voltage | Vcc | With signal | ±48 | V | | Peak Output Current | Io peak | Per channel | ±15 | A | | Power Dissipation | Pd | Tc = 25°C | 150 | W | | Junction Temperature | Tj | - | 150 | °C | | Operating Substrate Temp | Tc | - | -30 to +125 | °C | | Storage Temperature | Tstg | - | -40 to +150 | °C | You must use a sufficiently large heatsink. The thermal resistance (θj-c) is approximately 0.9°C/W.
