带关断的差分输入5V 130mW立体声直驱耳机功放

AiP9722B立体声耳机放大器是针对电路板空间优先的便携设备而设计的。AiP9722B采用独特的Direct-Drive结构，在单电源供电下能产生以地为参考的输出，可省去大容量隔直电容。 AiP9722B每个通道能够向16Ω负载提供70mW功率或向32Ω负载提供130mW功率，并且THD+N只有0.009%。217Hz频点具有80dB的电源抑制比（PSRR），使该器件可以工作在嘈杂的数字电源下，不需要额外的线性稳压器。全面的“咔嗒/噼噗”声抑制电路在启动与关断过程中可以抑制“咔嗒/噼噗”声。低功耗关断模式将电源电流减小到0.1μA。AiP9722B为外置电阻调节增益。 • 工作在2.4V至5.5V，单电源\n• 无需大尺寸隔直电容\n• 输出电容不会使低频响应变差\n• 增益可调\n• THD+N仅为0.009%\n• 低静态电流（5.5mA）\n• 放大器输出端具有±8KV ESD保护（人体模式）\n• 封装形式：TSSOP16/QFN16;
