HAA9210

    HAA9210是一颗单通道AB类音频功率放大器。在5V电源供电，THD+N=1%，8Ω负载上可以输出1.7W的功率。
    HAA9210的单端输入架构和极高的PSRR有效地提高了HAA9210对RF噪声的抑制能力。无需外部反馈电阻，极少的外围元件就能提供芯片稳定工作，大大减少了PCB面积并降低成本并简化了设计。快速地启动时间和纤小的封装尺寸使得HAA9210成为便携式音频产品的最佳选择。
    HAA9210具有极低的关断电流，极大的延长系统的待机时间。OTP、UVLO保护功能增强系统的可靠性。开启、关闭POP-click抑制功能改善了系统的听觉感受，同时简化系统调试。
    HAA9210提供带散热片的DFN2X2-8L封装。
