Product Descriptions

HT8513, integrated with adaptive sync boost converter, is a mono Class D audio amplifier that drives up to continuous 3W (<1% THD+N, 20-20kHz full band) into 4ohm speakerand 6.5W (10% THD+N, 1kHz) into 2ohm speaker from a Li-battery voltage. It also integrates Class AB amplifier.

The built-in sync boost converter generates a supplyvoltage of 6.2V for the audio amplifier. The boost converter is adaptive and is automatically active only when the peak output audio signal exceeds a preset voltage threshold, which is optimized to prevent clipping while maximizing system efficiency.

HT8513 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.

Class AB amplifier mode is also available for HT8513. Once the EMI Interference from class D and Boost Converterbecomes an annoying problem, HT8513 can be changed into Class AB mode.

HT8513 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.As for protection function, over current protection function for speaker output terminals, over temperature protection function are also prepared.
