The SY24108 is a Class-D audio power amplifier with analog input and high-power efficiency for driving bridge-tied stereo speakers with up to 2×20W/4Ω. The efficiency of the SY24108 eliminates the need for an external heat sink when playing music.

The SY24108 advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM/AF interferences; this is achieved together with an option of Master and Slave synchronization, making it possible to synchronize multiple devices.

The SY24108 is fully protected against faults including short circuit, over temperature, DC error, under voltage. The short circuit, over temperature and DC error protection includes an auto-recovery feature. The under voltage protection with hysteresis can be self-cleared.
