HT8313 - 5.5W mono high-fidelity audio power amplifier

General Description

HT8313 is a Class D audio amplifier which can deliver continuous 5.5W output power into a 4Ω speaker with 5V power supply when THD+N = 10%.

Key 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. Class AB amplifier mode is also available for HT8313. Once the EMI Interference from class D and Boost Converter becomes an annoying proble.
