HT6809 is a D-class audio power amplifier with an internal integration of 32-bit digital volume control and anti clipping distortion function, and ultra-low EMI stereo output free filter. Under the conditions of a power supply voltage of 5V, THD+N=10%, and a 4 Ω load, it can output up to 3W of power, providing performance comparable to AB class amplifiers while achieving an efficiency of up to 90% The biggest feature of HT6809 is its anti clipping distortion (ACF) output control function, which can detect and suppress output signal clipping distortion (broken sound) caused by excessive amplitude of input music and voice signals. It can also adaptively prevent output clipping caused by power voltage drop in battery applications, significantly improving sound quality, creating a very comfortable music experience, and protecting the speaker from overload damage. By externally connecting different resistance and capacitance values at the ACRC end, Flexibly set the sound quality and output power of the amplifier; At the same time, the chip provides ACF Off mode
