HT8312
5.2W Anti-Clipping Mono Class D/AB Audio Amplifier with Adaptive Charge Pump Regulator

HT8312 is a Class D audio amplifier which can deliver continuous 5.2W output power into a 4Ω speaker with 4.2V battery supply when THD+N = 10%. The class D audio amplifier’s power supply is adaptively boosted by the integrated charge pump regulator which only works while the output power is big enough. This will significantly extend the playing time in battery supply applications.

HT8312 features Anti-Clipping Function (ACF) which detects output signal clip due to the over input signal and suppresses the output signal clip automatically. Also, it can adapt the output clip caused by power supply voltage down. It can significantly improve the sound quality, creating a very comfortable musical enjoyment, and to protect the speakers from overload damage. It also provides ACF OFF mode.

Class AB amplifier mode is also available for HT8312. Once the EMI Interference from class D and Boost Converter becomes an annoying problem, HT8312 can be changed into Class AB mode.

HT8312 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.

HT8312 has an internal gain of 28dB and an independent Shutdown function which can minimize the power consumption. 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.
