60mW、DirectDrive、立体声耳机放大器，具有较低的RF干扰敏感度，带关断控制

MAX9724A/MAX9724B立体声耳机放大器是专为那些电路板空间很有限的便携式设备而设计的。这些器件采用独特的DirectDrive®架构，可在单电源供电时产生以地为参考的输出，无需大容量隔直电容，节省了成本，缩小了电路板空间，并降低了元件高度。MAX9724可以抑制由输入和电源迹线的天线效应引入的RF辐射，避免放大器不会对耦合进来的噪声进行解调。MAX9724A提供外部可调增益，而MAX9724B则具有-1.5V/V的内部预置增益。MAX9724A/MAX9724B每通道可向32Ω负载提供60mW功率，THD+N仅为0.02%。1kHz时高达80dB的电源抑制比(PSRR)使该 \n• 提高RF噪声抑制(高达67dB，远远优于典型放大器) \n• 无需大容量隔直电容 \n• 低功耗关断模式，< 0.1µA \n• 可调增益(MAX9724A)或-1.5V/V的固定增益(MAX9724B) \n• 0.02%的THD+N \n• 高PSRR (1kHz时80dB)，无需LDO \n• 内部集成有咔嗒-噼噗声抑制电路 \n• 采用2.7V至5.5V单电源供电 \n• 低静态电流(3.5mA) \n• 提供节省空间的封装 \n• 12焊球UCSP封装(1.5mm x 2mm) \n• 12引脚薄型QFN封装(3mm x 3mm x 0.8mm);
