CP2250-31阶增益可调3W、AB 类/D 类、立体声音频功放及耳机放大器

CP2250 是一款带 AB 类/D 类工作模式切换，带耳机放大功能，增益可调的立体声音频功放。可通过控制引脚使芯片在 AB类或者 D类两种工作模式间灵活切换，以匹配外围应用环境的变化。\n 当耳机插头接入插孔时，芯片将在单端 AB 类的工作模式下驱动立体声耳机。CP2250 将扬声器放大和耳机放大两种模式兼容实现，极大地简化了音频系统的设计复杂度。同时，芯片的免滤波 PWM 调制结构和输入、反馈电阻内置等特点减少了外部元件、PCB 面积及系统成本。\n CP2250 还具有 31 步可调增益，即在外围输入电阻固定的情况下，根据不同的应用环境，可由增益控制引脚加/减增益。最大增益为 - AB 类/D 类工作模式切换\r\n- 免滤波立体声输出\r\n- 最大输出功率(5.5V 供电，D 类，10%THD，4Ω): 3W/CH\r\n- 最大输出功率(5V 供电，D 类，1%THD，8Ω): 1.3W/CH\r\n- 低谐波失真及噪声(THD+N)\r\n- 高达 90%的工作效率(D 类工作模式)\r\n- 全带宽 EMI 抑制能力，无 FM 干扰\r\n- Pop-click 噪声抑制功能\r\n- 输出短路保护、过温保护、欠压保护\r\n- 立体声耳机放大功能\r\n- 31 步增益调节及静音功能\r\n- 宽工作电压范围：2.7V~5.5V\;
