The 1µH inductor in series with the output isolates cable capacitance from the amplifier's feedback loop.

Direct outputs for the three amplified channels. Typical Application Circuit Diagram

Approximately 50W to 100W per channel (depending on voltage and load). Operating Voltage: Dual power supply (typically ±30Vplus or minus 30 cap V ±45Vplus or minus 45 cap V stk413-430 circuit diagram

Simplifies PCB design and assembly.

The STK413-430 is a member of the STK series of hybrid integrated circuits, designed specifically for high-power stereo audio amplification. It is engineered with new Darlington power transistors in a pure complementary construction, which reduces crossover distortion and provides cleaner sound reproduction. Key Features and Specifications 2 (Stereo) Maximum Supply Voltage ( Vcccap V sub c c end-sub ): ±34.5Vplus or minus 34.5 cap V (Recommended operating range) Output Load Impedance: 8 Ωcap omega Ωcap omega

If the amplifier does not function correctly, check the following:

The internal hybrid circuitry handles the voltage and current gain. It utilizes a current mirror circuit to maintain low total harmonic distortion (THD). It is engineered with new Darlington power transistors

Pin-compatible within the STK413-xxx series, allowing for power output scaling without redesigning the PCB.
