Herun Booster

The HT8691R is a Class D audio power amplifier with a built-in BOOST boost module. The built-in BOOST boost module can adjust the boost value through an external resistor. Even when powered by a lithium battery, it can continuously output 11W power when boosted to 7.5V under 2 Ω load conditions. It supports external settings to adjust the BOOST output voltage The biggest feature of HT8691R is its anti clipping distortion (ACF) output control function, which can detect and suppress output signal clipping distortion (breaking) caused by excessive amplitude of input music and voice signals. It can also adaptively prevent output clipping caused by a drop in BOOST boost voltage, significantly improving sound quality, creating a very comfortable listening experience, and protecting the speaker from overload damage. At the same time, the chip has ACF-Off mode.
