HT8693, 10W anti-breaking sound mono class D audio amplifier 9W mono class AB audio amplifier

The HT8693 is an audio power amplifier with class D and class AB operating modes. In class D mode, under VDD=8.5V, THD+N=10%, 4Ω load, it can continuously output 10W power; in class AB mode, under VDD=8.5V, THD+N=10%, 4Ω load, It can continuously output 9W power.

The HT8693 has an anti-clipping distortion (ACF) output control function in the class D working mode, which can detect and suppress the clipping distortion (broken sound) of the output signal caused by the excessive amplitude of the input music and voice signals, which can significantly improve the sound quality and create Enjoy comfortable listening and protect your speakers from overload damage. At the same time, the chip also has an ACF-Off mode that can be configured.

The HT8693 can realize the free switching function of class AB and class D, and can switch to class AB audio power amplifier mode at any time when it is troubled by EMI interference of class D power amplifier.

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

HT6881, 4.7W Anti-Clipping Mono Audio Power Amplifier

The HT6881 is a low EMI, anti-clip distortion, mono filter-free Class D audio power amplifier. Under the condition of 6.5V power supply, 10%_THD+N, 4Ω load, the output power is 4.7W, maintaining high efficiency in various audio terminal applications and providing the performance of class AB amplifier.

The biggest feature of HT6881 is the anti-clip distortion (ACF) output control function, which can detect and suppress the clipping distortion (broken sound) of the output signal caused by the excessive amplitude of the input music and voice signals, and can also adaptively prevent the battery Output clipping caused by supply voltage drops in the application significantly improves sound quality, creates a very comfortable listening experience, and protects the speakers from overload damage. At the same time the chip has ACF-Off mode.

HT6881 has unique electromagnetic radiation (EMI) suppression technology and excellent full-bandwidth low radiation performance. The radiation level is still far below the FCC Part15 Class B standard without any auxiliary design, which not only avoids interference with other sensitive circuits but also reduces system design difficulty. It can also be switched to Class AB mode to completely eliminate electromagnetic radiation.

The HT6881 integrates filter-free digital modulation technology, which can directly drive the speaker and minimize the distortion and noise of the pulse output signal. The output requires no filtering network, and few external components save system space and cost, making it ideal for portable applications.

In addition, the built-in shutdown function of the HT6881 minimizes the standby current, and also integrates functions such as output over-current protection, on-chip over-temperature protection and power supply under-voltage abnormal protection.

HT6879, 3.5W Mono Class D Audio Power Amplifier with Digital Volume Control/Anti-clipping Low EMI

The HT6879 is a high-fidelity, ultra-low EMI, mono filter-free Class-D audio power amplifier with integrated 32-step digital volume control and anti-clip distortion function. Under the condition of 5V power supply, 10%_THD+N, and 4Ω load, it outputs 3.5W high power, maintains high efficiency in various audio terminal applications, and provides high-fidelity and low-noise performance of class AB amplifiers.

The AROC radiation and conducted interference suppression circuit enables the HT6879 to have excellent full bandwidth and low radiation performance. The radiation level when the output speaker cable is 20cm long without auxiliary filter design is far below the FCC Part15 Class B standard.

The HT6879's anti-clipping function detects and suppresses output clipping distortion (broken sound) caused by excessive music, voice signal amplitude, or battery voltage drop, significantly improving sound quality, creating a comfortable listening experience, and protecting speakers from noise. Damaged by overload. For different needs, the anti-sharp top has two modes, ACF-1 and ACF-2, corresponding to about 3% and 10% of the maximum THD+N, and the chip has ACF-Off mode.

The output of the HT6879 does not require a filter network, and few external components save system space and cost, making it ideal for portable applications.

In addition, the built-in shutdown function of the HT6879 minimizes the standby current, and also integrates functions such as over-current protection, over-temperature protection and under-voltage abnormal protection.

HT863, 10W Mono Hi-Fi Class D Audio Power Amplifier with Any Configuration Limiting Function

HT863 is a mono class D audio power amplifier. Under the condition of VDD = 9.0V, THD+N=10%, 4Ω load, 1kHz signal, it can continuously output 10W power; Customized to meet.

The HT863 has an arbitrarily configurable Limiter function. After the limiter function is turned on, even if the input signal is very large, the music output can be limited within the specified power and THD+N to meet the needs of different sound quality experience and speaker protection.

The HT863 also has an automatic temperature limit control (TFB) function. When the on-chip temperature is high under high power output and high ambient temperature, the chip can automatically reduce the system gain to avoid the chip from entering the over-temperature shutdown protection mode. Under the premise of ensuring music quality, the peak power of music can be significantly improved.

In addition, the HT863 integrates filter-free modulation technology, which can directly drive the speaker. The built-in shutdown function minimizes the standby current. It also integrates output over-current protection, on-chip over-temperature protection and power supply under-voltage abnormal protection.

HT6872, 4.7W Anti-Clipping Mono Class D Audio Power Amplifier

The HT6872 is a low EMI, anti-clip, mono filter-free Class D audio power amplifier. Under the condition of 6.5V power supply, 10%_THD+N, 4Ω load, the output power is 4.7W, maintaining high efficiency in various audio terminal applications and providing the performance of class AB amplifier.

The biggest feature of the HT6872 is the anti-clip distortion (ACF) output control function, which can detect and suppress the clipping distortion (broken sound) of the output signal caused by the excessive amplitude of the input music and voice signals, and can also adaptively prevent the battery Output clipping caused by supply voltage drops in the application significantly improves sound quality, creates a very comfortable listening experience, and protects the speakers from overload damage. At the same time the chip has ACF-Off mode.

HT6872 has unique electromagnetic radiation (EMI) suppression technology and excellent full-bandwidth low radiation performance. The radiation level is still far below the FCC Part15 Class B standard without any auxiliary design, which not only avoids interference with other sensitive circuits but also reduces system design difficulty.

The HT6872 integrates filter-free digital modulation technology, which can directly drive the speaker and minimize the distortion and noise of the pulse output signal. The output requires no filtering network, and few external components save system space and cost, making it ideal for portable applications.

In addition, the built-in shutdown function of HT6872 minimizes the standby current, and also integrates functions such as output over-current protection, on-chip over-temperature protection and power supply under-voltage abnormal protection.
