The SY24104A is an analog Class-D audio power amplifier. It has filterless operation control strategy which eliminates the LC filter for each channel to reduce the size of final product and the cost of mass production. It has high conversion efficiency for driving two bridge-tied stereo speakers with no need for an external heat sink when playing music. The spread spectrum operation mode is achieved internally to improve the EMI performance. The amplifier gain of SY24104A in audible bandwidth is selectable by the external pin. Fully short protection at output side against shorts to GND, V_DD and out-to-out is achieved with auto recovery capability.
