内置BOOST自适应升压_26.6W双声道G类音频功率放大器

\r\n LTK5327 是一款 26W 内置异步升压音频功率放大器，芯片具有自适应升压、防破音、 AB/D 类模式切换、自适应同时具备超低底噪、超低 EMI。自适应升压在输出幅度较小时升压电路不工作，功放直接由电源供电，当输出幅度较大时内部自动启动升压电路，自适应升压能提高电池续航时间，延长电池的使用寿命率。 LTK5327 有 2 种防破音模式可选择，能满足各种不同的需求，并且保护扬声器避免过载而损坏， 芯片具有 AB/D 类切换功能， AB 类时可减少功放对 FM 干扰。全差分结构有效的提高功放对 RF 噪声抑制。 • 输入电压范围 2.8V-5.5V\r\n• 内置异步 BOOST 升压\r\n• 自适应升压\r\n• 两种防破音模式（ALC）\r\n• 无需滤波器 D 类放大器、低静态电流和低EMI\r\n• 超低底噪、 超低失真\r\n• THD+N=10%， VBAT=4.2V， 3Ω +22UH 负载下提供高达 26.6W 的输出功率\r\n• THD+N=1%， VBAT=4.2V,3Ω +22UH 负载下提供高达 25.2W 的输出功率\r\n• 短路保护、欠压保护、过温保护;
