HT6828
4.7W Anti-Clipping Stereo Class D Audio Power Amplifier
HT6828 is a low-EMI, Anti-Clipping, filter-less, monaural Class D audio power amplifier IC with maximum output power of 2×4.7W. It has a high efficiency in a variety of audio terminal applications with Class AB amplifier performance。HT6828 features Anti-Clipping Function (ACF) which detects and suppresses output signal clippings due to the over level inputs of music or voice signals. The ACF function also can adapt the output clippings caused by power supply voltage down in battery applications. It improves acoustical quality considerably, gives great listening enjoyment, and prevents speaker from overload damaging.HT6828 has excellent EMI radiation suppression characteristics. The radiation level is well below FCC Part15 Class B standards without any additive design. It keeps from interference with other EMI sensitive circuits, simplifies system design and lowers system cost.HT6828 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.HT6828 has shutdown mode, over-current protection, over-temperature protection and low supply voltage malfunction preventing function.
