Datasheet ((exclusive)) — Stk412530
The STK412-530 is a two-channel, high-power audio amplifier IC originally manufactured by Sanyo. It belongs to a series of Class H hybrid ICs that utilize a built-in shift power supply circuit to achieve high efficiency by switching supply voltages based on input signal levels. Key Technical Specifications
Technical Specifications
The STK412-530 has a 20-pin SIP (Single In-line Package) configuration. The pinout is as follows: stk412530 datasheet
- Power Supply Pins: Positive ($+V_CC$) and Negative ($-V_CC$) rails. These are usually the thicker pins designed to handle higher current.
- Ground Pins: Connected to the chassis ground or signal ground.
- Input Pins: The signal entry point for the left and right channels.
- Output Pins: The connection point that drives the loudspeakers.
- Mute/Standby Pins: Many modern STK modules include a muting function to prevent "pop" sounds during power-up.
: To achieve full power, a transformer with a secondary voltage of 30V-35V AC and at least a 5A current rating The STK412-530 is a two-channel, high-power audio amplifier
