Stk413-430 Circuit Diagram

Several similar models exist with different power ratings but identical pinouts and application circuits:

Located on the opposite end or center, featuring low-impedance pins to drive the Left and Right speakers directly.

Note: Always cross-reference your specific module with its official datasheet for precise pin functionality, as variations exist among similar STK series ICs. stk413-430 circuit diagram

When designing or tracing a PCB for the STK413-430, follow these rules:

Always refer to the original Sanyo datasheet for exact values, but the standard application circuit described here remains valid for 99% of use cases. Whether you are chasing distortion, quiet hum, or simply building from scratch, the STK413-430 is a capable and rewarding audio building block. Several similar models exist with different power ratings

: Designed for a split power supply with a maximum supply voltage of Key Features

The negative feedback loop determines the overall voltage gain of the amplifier block. A voltage divider connected between the channel speaker output pin and the negative feedback pin sets the target gain. A series electrolytic capacitor in the NFB loop keeps the DC gain at unity, securing a near-zero DC output offset at the speaker terminals.
