Product Descriptions

HT863 is a single channel D-class audio power amplifier that can continuously output 10W power under VDD=9.0V, THD+N=10 percent, 4 Ω load, and 1kHz signal conditions; In addition, if there are AB class requirements, they can be customized to meet.

HT863 has a configurable Limiter function. After the amplitude limiting function is enabled, even if the input signal is large, the music output can be limited to the specified power and THD+N, meeting the needs of different sound quality experiences and protecting the speaker.

It also has an automatic temperature limiting control (TFB) function, which can automatically reduce the system gain when the temperature inside the chip is high due to high power output, high environmental temperature, etc., avoiding the chip from entering the over temperature shutdown protection mode, and significantly improving the peak power of music while ensuring music quality.

In addition, the HT863 integrates filter free modulation technology internally, which can directly drive the speaker. The built-in turn off function minimizes standby current, and also integrates functions such as output overcurrent protection, on-chip over temperature protection, and power supply undervoltage abnormal protection.
