fails, it often exhibits low output, high distortion, or instant speaker protection activation. Disclaimer: Ensure proper ESD protection and power handling
The is a classic example of Sanyo's thick-film hybrid integrated circuits, specifically designed as a two-channel shift power supply audio power amplifier . Unlike standard monolithic ICs, these hybrid modules house multiple semiconductor dies—like power transistors and resistors—mounted side-by-side on a ceramic substrate, creating a compact yet high-performance "black box" for high-fidelity audio equipment.
