The SY24105B is a Class-D audio power amplifier with analog input and high-power efficiency for driving bridged-tied mono speaker with up to 60W/4Ω. The high efficiency of the SY24105B eliminates the need for an external heat sink when playing music.

The SY24105B advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM interference, this is achieved together with an option of Master and Slave synchronization, making it possible to synchronize multiple devices.

The SY24105B is fully protected against faults including short circuit, over temperature, DC error, under voltage and over voltage. The short circuit, over temperature and DC error protection includes an auto-recovery feature. The under voltage and over voltage protection with hysteresis can be self-cleared.
