Stk413-430 Circuit Diagram -

Designed to minimize Total Harmonic Distortion (THD) for high-fidelity sound reproduction. Split Power Supply: Often utilizes a dual/split power supply (typically plus or minus voltage) to improve dynamic range and reduce noise. Circuit Implementation and Design

Power Supply: AC 22V-0-22V --> Bridge --> +VCC (Pin1,15) / GND / -VCC (Pin4,13) 4700µF each rail + 0.1µF bypass. stk413-430 circuit diagram

The internal schematic (found in the official Sanyo datasheet) shows that pins 5 and 12 (INV-) are the inverting inputs, which are used to set closed-loop gain with external resistors. Designed to minimize Total Harmonic Distortion (THD) for
