Stk413-430 Circuit | Diagram

High-current audio driving nodes routed directly to speakers through the protection circuit.

Capable of delivering up to 100W per channel (depending on load impedance and power supply voltage) [1].

Multiple pins dedicated to the positive and negative power supplies ( +VCCpositive cap V sub cap C cap C end-sub −VCCnegative cap V sub cap C cap C end-sub

resistor) is usually added between the output and ground. This prevents high-frequency oscillation and keeps the amplifier stable under varying speaker loads. stk413-430 circuit diagram
