HT8310
内置电荷泵升压音频功放
内置高效率自适应电荷泵升压，防削顶失真功能，D/AB切换的
5.2W单声道音频功率放大器
特点
概述
HT8310 是 一 款 D 类 音 频 功 率 放 大 器 ， 在
・4种防削顶失真功能(Anti-Clipping Function, ACF)
・自适应电荷泵升压功能
VBAT=4.2V、THD+N=10%，4Ω负载条件下能连续输
出5.2W功率。该D类功放的电源电压由内置的自适应
电荷泵升压模块提供。该升压模块在低功率时不升
压，可有效提升电池的播放时间。
・内部固定28dB增益
・输出功率
5.2W (VBAT=4.2V, RL=4Ω, THD+N=10%)
4.0W (VBAT=3.7V, RL=4Ω, THD+N=10%)
3.0W (VBAT=3.3V, RL=4Ω, THD+N=10%)
・效率
84% (VBAT=3.7V, RL=4Ω, 0.4W)
75% (VBAT=3.7V, RL=4Ω, 2W)
・电源
HT8310的最大特点是防削顶失真（ACF）输出
控制功能，可检测并抑制由于输入音乐、语音信号幅
度过大所引起的输出信号削顶失真（破音），也能自
适应地防止在升压电压下降所造成的输出削顶，显著
提高音质，创造非常舒适的听音享受，并保护扬声器
免受过载损坏。其具有4种不同的ACF模式，可针对
不同应用场合。同时芯片还具有ACF-Off 模式。
-升压输入VBAT：2.7V至5.5V
-升压输出CPOUT：6.4V
・静态工作电流：3mA
・关断电流：<1uA
・AB/D类可切换
HT8310具有AB类和D类的自由切换功能，在受
到D类功放EMI干扰困扰时，可随时切换至AB类音频
功放模式（此时电荷泵升压功能关闭）。
・免滤波器数字调制，直接驱动扬声器
・保护功能:过流/过热/欠压异常保护功能
・无铅封装， SOP16L-PP, QFN16L-PP
HT8310内部集成免滤波器数字调制技术，能够
直接驱动扬声器，并最大程度减小脉冲输出信号的失
真和噪音。输出无需滤波网络，极少的外部元器件节
省了系统空间和成本，是便携式应用的理想选择。
应用
此外，HT8310内部固定28dB增益，内置的关断
功能使待机电流最小化，还集成了输出端过流保护、
片内过温保护和电源欠压异常保护等功能。

HT8310
Audio Amplifier Integrated with Charge Pump
5.2W Anti-Clipping Mono Class D/AB Audio Amplifier with
Adaptive Charge Pump Regulator
FEATURE
GENERAL DESCRIPTION
HT8310 is a Class D audio amplifier which can
deliver continuous 5.2W output power into a 4Ω
speaker with 4.2V battery supply when THD+N =
10%. The class D audio amplifier’s power supply is
adaptively boosted by the integrated charge pump
regulator which only works while the output power
is big enough. This will significantly extend the
playing time in battery supply applications.
・4 modes of Anti-Clipping Function (ACF)
・Adaptive Charge Pump Regulator
・Maximum Voltage Gain: 28dB
・Output Power
5.2W (VBAT=4.2V, RL=4Ω, THD+N=10%)
4.0W (VBAT=3.7V, RL=4Ω, THD+N=10%)
3.0W (VBAT=3.3V, RL=4Ω, THD+N=10%)
・Efficiency
HT8310 features Anti-Clipping Function (ACF)
which detects output signal clip due to the over
input signal and suppresses the output signal clip
automatically. Also, it can adapt the output clip
caused by power supply voltage down. It can
significantly improve the sound quality, creating a
very comfortable musical enjoyment, and to protect
the speakers from overload damage. It provides 4
different ACF modes and ACF OFF mode to adjust
different applications.
Class AB amplifier mode is also available for
HT8310. Once the EMI Interference from class D
and Boost Converter becomes an annoying
problem, HT8310 can be changed into Class AB
mode.
HT8310 has a filter-less modulation circuit
which directly drives speakers while realizes low
distortion and low noise characteristics. Thanks to
filter-less, circuit design with fewer external parts
can be made in portable applications.
HT8310 has an internal gain of 28dB and an
independent Shutdown function which can
minimize the power consumption. As for protection
function, over current protection function for
speaker output terminals, over temperature
protection function, and low supply voltage
malfunction preventing function are also prepared.
84% (VBAT = 3.7V, RL = 4 Ω, Po = 0.4W)
75% (VBAT = 3.7V, RL = 4 Ω, Po = 2.0W)
・Power Supply
-Input VBAT：2.7V to 5.5V
-Output CPOUT：6.4V
