Stk412530 Datasheet -

The 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

For full technical diagrams and pinout configurations, refer to the STK412-530 Datasheet STK412-530 SANYO SIP-ZIP Modules - Veswin Electronics stk412530 datasheet

Measure the voltage at the output pins (before the relay). If you see high DC voltage (close to the rail voltage), the IC is blown. The is a two-channel, high-power audio amplifier IC

SIP-ZIP (Single In-line Package / Zig-Zag In-line Package). Impedance: Suitable for driving speakers up to 4 ohms. If you see high DC voltage (close to

: Uses a class H-like shift power supply circuit to reduce power loss during amplification. Application & Circuit Implementation
