The HT8693 is an audio power amplifier with both Class D and Class AB operating modes. Class D mode, VDD=8.5V, THD+N=10%, 4Ω load, can continuously output 10W power; Class AB mode, under VDD=8.5V, THD+N=10%, 4Ω load, can continuously output 9W power.
    HT8693 has anti-clipping distortion (ACF) output control function in Class D operating mode, which can detect and suppress output signal clipping distortion (broken sound) caused by excessive input music and speech signal amplitude, significantly improve sound quality, create comfortable listening enjoyment, and protect speakers from overload damage. At the same time, the chip also has ACF-Off mode configurable.
    HT8693 can realize the free switching function of Class AB and Class D, and can switch to Class AB audio power amplifier mode at any time when it is troubled by Class D amplifier EMI interference.
    In addition, the HT8693's built-in turn-off function minimizes standby current and integrates functions such as output overcurrent protection, on-chip overtemperature protection and power undervoltage protection.
    The HT8693 is available in a SOP8L-PP package.
