Product Descriptions

HT8693 is an audio power amplifier with two operating modes: Class D and Class AB. In Class D mode, it can continuously output 10W power under VDD=8.5V, THD+N=10 percent, and 4 Ω load; In AB mode, under VDD=8.5V, THD+N=10 percent, and 4 Ω load, it can continuously output 9W power.

HT8693 has an anti clipping distortion (ACF) output control function in Class D operating mode, which can detect and suppress output signal clipping distortion caused by excessive amplitude of input music and voice signals (broken)

Sound quality is significantly improved, creating a comfortable listening experience and protecting the speaker from overload damage. At the same time, the chip also has ACF-Off mode configurable.

HT8693 can achieve the free switching function between Class AB and Class D. When encountering EMI interference from Class D power amplifiers, it can switch to Class AB audio power amplifier mode at any time.

In addition, the built-in shutdown function of HT8693 minimizes standby current and integrates functions such as output over-current protection, on-chip over-temperature protection, and power supply undervoltage abnormal protection.
