Product Descriptions

HT3163 is a mono efficient, Class AB/D audio amplifier. In class D mode, the device can drive a speaker up to 40W/4 Ω at VDD = 18V. In class AB mode, the device can drive a speaker up to 17W/4 Ω at VDD = 12V.

Advanced EMI Suppression enables the use of inexpensive ferrite bead filters while meeting EMC requirements for system cost reduction. 

HT3163 is protected with Undervoltage, Overtemperature, and Overcurrent protection. 

HT3163 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 improve the sound quality, creating a very comfortable musical enjoyment, and to protect the speakers from overload damage.
