Stk412-230 Datasheet Pdf

Measurable high DC voltage (equal to Vcc rails) directly on pins 12 or 13. Do not connect speakers in this state.

Commonly found in home theater systems, stereo receivers, and even some high-performance vacuum cleaner motor modules. Stk412-230 Datasheet Pdf

rails are delivering symmetrical positive and negative voltages. A blown fuse on one rail will cause severe audio distortion or trigger protection mode. Measurable high DC voltage (equal to Vcc rails)

2-Channel (Stereo) or multi-channel configuration support Load Impedance: Optimized for 6 Ωcap omega Ωcap omega Total Harmonic Distortion (THD): < 0.4% at rated power Frequency Response: 20 Hz to 20 kHz Maximum Supply Voltage ( VCCcap V sub cap C cap C end-sub max): ±plus or minus ±plus or minus 70V (varies between high and low supply rails) 2. Pinout Configuration and Description Before soldering the new chip in place, test

Due to high power, a substantial heatsink is mandatory to manage thermal dissipation.

Before soldering the new chip in place, test the external emitter resistors (usually large, white ceramic block resistors rated at 0.22 to 0.47 ohms). If the original IC shorted out, it may have blown these resistors open. Installing a new IC with open emitter resistors will prevent the amplifier from working or damage the new chip.
