HT97230
带有3D环绕和低音增强的125mW免输出耦合电容 立体声线路驱动器/耳机放大器
HT97230为差分发送、可随便输入的线路图安装变频器/苹果耳机子增加器。5V配电时,配件为1kΩ装载带来3VRMS输入安装安装驱使程序;3.3V配电时,为600Ω装载带来2VRMS输入安装安装驱使程序。5V配电时,配件为32Ω苹果耳机子装载带来125mW安装安装驱使程序。IC兼有6dB组织结构放置增加收益,也可合理利用外链电容设施增加收益(现有仅带来外链电容设施增加收益手机手机版本,别的手机手机版本需预约)。IC在一整个语音频段内带来优质的THD+N。

HT97230有两个不同开启时间(tON)版本,版本A、C和E的导通时间tON为5.5ms,用于耳机驱动;B和D则具有130ms的tON,用于机顶盒设计(目前仅提供A版本,其他版本需预定)。内部电荷泵对输入电源反相,产生负电源。放大器的输出级由输入正电源和电荷泵输出负电源供电,双极性供电使得输出偏置在零电位,省去了大尺寸、容易引入失真的输出耦合电容。ICSD开关时没有咔嗒/噼噗声。

HT97230兼有3D旋转经营策略,能在三维立体声蓝牙耳机子上造就3D旋转声的体验。HT97220另外还有兼有低音明显增进学习经营策略,可重要依据蓝牙耳机子频响功能,对其他频段的低音展开各不相同因素的增加明显增进学习,提高低音明显增进学习的感觉。HT97230保证无铅无卤QFN24L-PP打包芯片封装,保证QFN20L-PP打包芯片封装的制定的需求。
