HT8696,7 is a filter-less stereo Class D audio power amplifier IC with maximum output power of 2×9.5W at VDD = 8.5V, THD+N = 10%, RL = 4Ω. HT8697 can also work in Class AB mode with maximum instantaneous output power of  2×9.0W at VDD = 8.5V, THD+N = 10%, RL = 4Ω.HT8696,7 features Anti-Clipping Function (ACF) which detects output signal clip due to the over input signal and suppresses the output signal clip automatically. Also the ACF function can adapt the output clip caused by power supply voltage down with battery. It can significantly improves the sound quality, creating a very comfortable musical enjoyment, and to protect the speakers from overload damage. It also supplies ACF OFF mode.HT8696,7 has a filter-less modulation circuit which directly drives speakers while realizes low distortion and low noise characteristics. Thanks to filter-less, circuit design with fewer external parts can be made in portable applications.HT8697 are free to change modes between Class AB and Class D. While in Class AB mode, EMI is not concerned as a problem as Class D mode.HT8696,7 has the independent Shutdown function which can minimize the power consumption at standby function. As for protection function, over current protection function for speaker output terminals, over temperature protection function, and low supply voltage malfunction preventing function are also prepared.
