The is a legendary, high-performance two-channel thick-film hybrid audio power amplifier integrated circuit (IC) originally engineered by Sanyo (now part of ON Semiconductor). Highly praised by audiophiles and hardware repair engineers, this module is widely used in high-fidelity (Hi-Fi) home theater receivers, professional sound gear, and custom audio setups. Operating on an efficient Class H topology with dynamic high/low dual power supply rail shifting, it delivers up to 120W to 150W per channel of clean analog power into a 6-ohm load while drastically cutting down on thermal waste.
: To achieve full power, a transformer with a secondary voltage of 30V-35V AC and at least a 5A current rating
The module is recognized for its "shift power supply" technology, which switches supply voltage based on the input signal level to maximize efficiency. : Delivers 150W + 150W (300W total). Operating Voltage : Maximum (no signal): ±69Vplus or minus 69 cap V Maximum (signal present, ±62Vplus or minus 62 cap V Recommended bipolar supply: ±40Vplus or minus 40 cap V ±50Vplus or minus 50 cap V By adhering to the guidelines in the ,
To maintain ultra-low Total Harmonic Distortion (THD) and pristine audio fidelity, the module should be powered safely below its absolute maximums. Split dual supplies at (High Rail) and (Low Rail).
To ensure reliability, the IC must operate within strict thermal and electrical limits: Maximum Supply Voltage ( cap V sub cap H plus or minus 95 cap V (No signal). Maximum Supply Voltage ( cap V sub cap L plus or minus 61 cap V (No signal). Operating Substrate Temperature 125 raised to the composed with power cap C Short-Circuit Tolerance : Allowable load shorted time is approximately 0.3 seconds. Built-in Protection Systems
